How do you verify the experiment the magnetic field lines are closed loops?

(i) Take a wooden plank and make a hole and place it on a table. (ii) Now place a retort stand on this plank and suspend a copper wire from the retort stand and see that the wire passes through the hole. iii) Connect a battery and switch and place a magnetic compass at the hole.

Does magnetic force cause circular motion?

The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion. (Note that because the charge is negative, the force is opposite in direction to the prediction of the right-hand rule.)

Are magnetic fields always circular?

Magnetic field lines aren’t always circular it’s just that the most simple magnetic fields (those around wires or solenoids) are circular or elliptical. Really though, magnetic field shapes are just dependent on the movement and distribution of charge.

How do you prove electromagnetic induction?

Quote:
And this phenomena is called electromagnetic induction so electromagnetic induction is a phenomenon in which when you change the magnetic field through a coil it induces a voltage or a current.

What is Faraday experiment?

When Michael Faraday made his discovery of electromagnetic induction in 1831, he hypothesized that a changing magnetic field is necessary to induce a current in a nearby circuit. To test his hypothesis he made a coil by wrapping a paper cylinder with wire.

How does Faraday’s experiment work?

Faraday connected his apparatus to a battery, which sent electricity through the wire creating a magnetic field around it. This field interacted with the field around the magnet and caused the wire to rotate clockwise. This discovery led Faraday to contemplate the nature of electricity.

How do you test Faraday’s Law?

Your first task is to observe Faraday’s/Lenz’ Law in action. To observe these laws, simply connect the coil to the multimeter and examine what happens to the emf when the magnet is in motion through the coil.

What is the difference between Faraday’s law and Lenz’s law?

While Faraday’s law tells us the magnitude of the EMF produced, Lenz’s law tells us the direction that current will flow. It states that the direction is always such that it will oppose the change in flux which produced it.
