A circular coil of 15 turns of radius 10 cm was placed in a uniform magnetic field. This coil is placed in the magnetic field at an angle of 30 degrees with the surface normal. As the magnetic flux density B increases from 1 T to 5 T within 10 seconds, calculate the induced voltage in the coil. Also, show the direction of the current flowing through the coil as B decreases in the direction shown.

Step 1

The magnetic flux through the coil is given by the formula: Φ = B*A*cos(θ) where B is the magnetic flux density, A is the area of the coil, and θ is the angle between the magnetic field and the surface normal. In this case, B increases from 1 T to 5 T, so we need Show more…
