Problem: A 100-turn, 4.0-cm-diameter coil is at rest in a horizontal plane. A uniform magnetic field 60° away from vertical increases from 0.50 T to 2.0Tin 0.90s .What is the induced emf in the coil?

FREE Expert Solution

Induced emf:

ε=-dϕBdt

Magnetic flux:

ϕB=NBAcosθ

The normal of the area of the coil points vertically. The magnetic field points 60° from the vertical. 

The angle between the area and the magnetic field is 60°.
