Answer 2

left hand rule is defined as. the rate at which the magnetic flux linked with a coil changes, produces the induced emf or current. more the rate, more the current and vice -versa.
Right hand thumb rule : hold the wire carrying current in your right hand, such that the thumb indicates the direction of current, then the folded fingers will indicate the presence of magnetic field (lines) surrounding the wire ( I think the answer is up to mark)
