Identify the poles of the magnet in the given figure.

State the rule which you use to find the direction of induced current or state Fleming's right-hand rule.

The induced electromotive force $(EMF)$ in a conducting coil does not depend on which of the following?

Draw the patterns of magnetic field lines due to a bar magnet. The magnetic field lines are closed curves. Why?

State Faraday's first law of electromagnetic induction.

$(a)$ An electric current is passed in a horizontal copper wire from east to west. Explain your observations when a compass needle is placed $(i)$ below this wire,$(ii)$ above the wire. Draw inference from your observations.
$(b)$ List the factors on which the strength of the magnetic field due to a straight conductor carrying current depend. How should these be changed to decrease magnetic field at a point?
