A bar magnet with North Pole facing towards a coil moves as shown in figure. What happens to the magnetic flux passing through the coil?

The direction of current flowing in a coil is shown in figure. What type of magnetic pole is formed at the face that has flow of current as shown in figure.

Why does the picture appear distorted when a bar magnet is brought close to the screen of a television? Explain.

Explain the working of electric motor with a neat diagram.

The value of magnetic field induction which is uniform is $2 \mathrm{T}$. What is the flux passing through a surface of area $1.5 {\mathrm{m}}^2$ perpendicular to the field?

A force of $8 \mathrm{N}$ acts on a rectangular conductor $20 \mathrm{cm}$ long placed perpendicular to a magnetic field. Determine the magnetic field induction if the current in the conductor is $40 \mathrm{A}$.

How do you verify experimentally that the current carrying conductor experiences a force when it is kept in magnetic field?
