The induced current is highest when the direction of motion of the coil is at 90° or perpendicular with respect to the magnetic field, as the flux cutting is maximum in this case.
What is the biggest problem in physics?
However, there are some problems in physics that the Standard Model can’t solve. One of the biggest is the existence of dark matter. Dark matter is a mysterious form of matter that we can’t see, but accounts for nearly all the calculated mass in the Universe.
What is the most difficult physics question?
1. What is matter made of? We know matter is made up atoms, and atoms are made up of protons, neutrons, and electrons. And we know that protons and neutrons are made up of smaller particles known as quarks.
What is the hardest physics equation?
Yet only one set of equations is considered so mathematically challenging that it’s been chosen as one of seven “Millennium Prize Problems” endowed by the Clay Mathematics Institute with a $1 million reward: the Navier-Stokes equations, which describe how fluids flow.

- Does God exist? –
- How big is space? –
Is antimatter a real thing?
Although it may sound like something out of science fiction, antimatter is real. Antimatter was created along with matter after the Big Bang. But antimatter is rare in today’s universe, and scientists aren’t sure why.
What is the hardest question ever?
Science is based on the correspondence theory of truth, which claims that truth corresponds with facts and reality. Various philosophers have put forth substantive challenges to the truth claims made by science.

What are the 7 hardest math problems?
Clay “to increase and disseminate mathematical knowledge.” The seven problems, which were announced in 2000, are the Riemann hypothesis, P versus NP problem, Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier-Stokes equation, Yang-Mills theory, and Poincaré conjecture.
Is physics harder than chemistry?
Physics is considered comparatively harder than chemistry and various other disciplines such as psychology, geology, biology, astronomy, computer science, and biochemistry. It is deemed difficult compared to other fields because the variety of abstract concepts and the level of maths in physics is incomparable.
The Navier-Stokes equation is difficult to solve because it is nonlinear. This word is thrown around quite a bit, but here it means something specific. You can build up a complicated solution to a linear equation by adding up many simple solutions.
Which topic is best for project in physics?
- Physics Projects on Electromagnetic Induction and Alternating Currents.
- Physics Projects on Current Electricity.
- Physics Projects on Electrostatics.
- Physics Projects on Magnetic Effects of Current and Magnetism.
- Physics Projects on Optics.
- Physics Projects on Oscillations and Waves.
- Modern Physics Topics for Project.
Do time crystals exist?
Lazarides acknowledged that the current experiments with time crystals are far from any practical applications, whatever they might be, but the chance to learn more about quantum mechanics is invaluable. Time crystals are “something that doesn’t actually exist in nature,” he said.
How do you find maximum emf?
- E = BANωsinθ = BANωsin(ωt) The maximum value of the e.m.f (Eo) is when θ (= ωt) = 90o (that is, the coil is in the plane of the field, Figure 2) and is given by.
- Maximum e.m.f (Eo) = BANω
- The r.m.s value of the e.m.f is (Er.m.s) = BANω/21/2
Why is emf max when flux is zero?
Newton, Galileo and Einstein have all been called “Fathers of Modern Physics.” Newton was called this because of his famous law of motion and gravitation, Galileo for his role in the scientific revolution and his contributions on observational astronomy, and Einstein for his groundbreaking theory of relativity. Q.
Is induced current the same as emf?
By Faraday’s law, the magnitude of the induced emf is equal to the rate of change of magnetic flux, so its maximum values occurs when the flux curve has its greatest slope. The induced emf goes through zero when the flux curve has zero slope.
Which is the most mysterious question in the world?
- What is the universe made of?
- How did life begin?
- Are we alone in the universe?
- What makes us human?
- What is consciousness?
- Why do we dream?
- Why is there stuff?
- Are there other universes?
What’s a question no one can answer?
An induced current is produced by a changing magnetic field. There is an induced emf associated with the induced current. A current can be produced without a battery present in the circuit. Faraday’s law of induction describes the induced emf.
What is a good physics question?
Do caterpillars know that they’re going to be butterflies or do they build the cocoon not knowing what will happen? If God sneezed, what would you say? If we evolved from monkeys, why are there still monkeys? If life is so short, why do we do things that we don’t like and like so many things that we don’t do?
What can 1 gram of antimatter do?
Is light a particle or a wave? Is metal a good heat shield? Is the reason that nothing can go faster than light because we have not tried hard enough? Is there any difference between antimatter, dark matter, dark energy, and degenerate matter?
Do bananas create antimatter?
A gram of antimatter could produce an explosion the size of a nuclear bomb. However, humans have produced only a minuscule amount of antimatter. All of the antiprotons created at Fermilab’s Tevatron particle accelerator add up to only 15 nanograms.
Can I create antimatter?
A banana is a good source of fiber, vitamin C, manganese, and a host of other goodies. It’s also a good source of antimatter. That’s because a banana contains a tiny amount of a radioactive form of potassium. As the element decays, it produces positrons, the antimatter counterpart of electrons.
What’s the biggest question in life?
For the past 50 years and more, laboratories like CERN have routinely produced antiparticles, and in 1995 CERN became the first laboratory to create anti-atoms artificially. But no one has ever produced antimatter without also obtaining the corresponding matter particles.
