Acylindrical coil has 400 turns and a radius of 2.00 cm. the external magnetic field in the region of the coil is uniform and axial. the field rises from 6.00 x 10^-2 t to 13.0 x 10^-2 t in 2.00 minutes. find the induced emf across the ends of the coil. the ends of the coil are attached to a resistor of 6.00 ohms. find the induced current i.

2.93 x 10⁻⁴ Volts

Explanation:

N = number of turns in the cylindrical coil = 400

r = radius = 2 cm = 0.02 m

A = Area = πr² = (3.14) (0.02)² = 0.001256 m²

ΔB = Change in magnetic field = 0.13 - 0.06 = 0.07 T

t = time interval = 2 min = 2 x 60 s = 120 s

R = resistance of the resistor = 6 Ω

Induced emf between the ends of coil is given as

E = 2.93 x 10⁻⁴ Volts

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
