Explanation Write the expression to calculate the magnetic flux through the loop. Φ B = B A cos θ (I) Here, Φ B is the magnetic flux, B is the magnetic field, A is the area of the loop and θ is the angle between the normal to the loop and magnetic field. Write the expression for the induced emf by Faraday law. E = | − N d d t ( Φ B ) | (II) Here, E is the induced emf and N is the number of turns. Write the expression for the area of the loop. A = π r 2 (III) Here, r is the radius of the loop. Substitute B A cos θ for Φ B and π r 2 for A in equation (II). E = | − N d d t ( B π r 2 cos θ ) | = | − ( N π r 2 cos θ ) d B d t | (IV) Conclusion: Substitute 0

A 36-turn circular coil of radius 3.60 cm and resistance 1.00 is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time according to the expression B = 0.010 0t + 0.040 0t², where B is in teslas and t is in seconds. Calculate the magnitude of the induced emf in the coil at t = 4.40 s. mV

A 30-turn circular coil of radius 7.0 cm and resistance 4.0 is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time according to the expression , where t is in seconds and B is in tesla. Calculate the induced emf in the coil at t = 3.0 s.

A coil with 35 turns sits in a magnetic field. The cross-sectional area of the coil is 5.1 cm2. If the magnetic field uniformly reduces from 1.0×101 T to 1.5 T in 6.5 seconds, what is the magnitude of the induced emf in that coil?
