Magnitude of e.m.f. produced in a coil when a magnet is inserted into it does no
Magnitude of e.m.f. produced in a coil when a magnet is inserted into it does not depend upon:
- A. Number of turns in the coil
- B. Speed of the magnet
- C. Magnetic strength of magnet
- D. Temperature of coil
Step-by-step solution
According to Faraday's law, the induced e.m.f. is given by ε = -N(dΦ/dt), depending on number of turns (N), rate of change of magnetic flux (dΦ/dt) which depends on speed of magnet and magnetic strength, but not on temperature of the coil.
