A single loop of wire with an area of 0.0900m2 is in a uniform magnetic field that has an initial value of 3.80 T, is perpendicular to the plane of the loop, and is decreasing at a constant rate of 0.190 T/s. (a) What emf is induced in this loop? (b) If the loop has a resistance of 0.600Ω, find the current induced in the loop.

The induced loop in coil is 0.0171 V and induced current in the loop is 0.0284 A

Explanation:

Given:

Area of loop

Initial magnetic field T

Rate of magnetic field

(a)

From the formula of faraday's law,

Induced emf is given by,

Where magnetic flux

Put the value of in above equation,

  V

(b)

Resistance 0.600Ω

The induced current in the loop is given by,

  A

Therefore, the induced loop in coil is 0.0171 V and induced current in the loop is 0.0284 A

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
