When a current can create a magnetic field then conversely changing magnetic filed may also generate current.
a) True
b) False
2.
A strong constant flux generates stronger induced emf.
a) False
b) True
3.
The product of induced current and resistance of the loop is always constant.
a) True

4.
The rotation of coil in a magnetic filed give rise to motional emf.
a) True

5.
The induced emf is inversely proportional to the rate of change of magnetic flux through the coil.
a) False
