Question

When considering electromagnetic induction:

True or False ....

Electric current can be induced by a changing magnetic field.

The smaller the change in magnetic flux, the greater the induced emf.

Whenever a wire coil moves linearly inside a uniform and time independent magnetic field, an emf is produced across its ends.

Faraday's Law can be used to calculate the magnitude of an induced emf.

Lenz's Law determines the magnitude of the emf induced across the ends of a coil of wire that is rotating in a magnetic field.

Electric current is inuced by change in magnetic field. hence, it is true.

The statement, the Smaller the change in flux, the greater the induced emf is flase.

Faradays law is used to determine the magnetic of an induced emf. hence, it is true.

Lense law says that the induced currents will oppose the change in field. Hence, the statement is false.
