Electromagnetic Induction Problems - 01

A loop of wire of area 1m² is placed perpendicular to a uniform magnetic field of 1Wbm^-². If the field is uniformly increased to 2Wbm^-² in a time of 10 seconds, find the induced EMF.

Suggested solution:

A = 1m², B₁ = 1Wbm^-², B₂ = 2 Wbm^-², t = 10s, E = ?

Initial magnetic flux, f₁ = B₁A = 1Wbm^-² x 1m² = 1Wb

Final magnetic flux, f₂ = B₂A = 2Wbm^-² x 1m² = 2Wb
