You are looking down on a n = 9 turn coil in a magnetic field b = 0.5 t which points directly down into the screen. if the diameter of the coil d = 3 cm, and the field goes to zero in t = 0.14 seconds, what would be the magnitude of the voltage (in volts) and direction of the induced current? indicate the direction of the current by the sign in front of your voltage: counterclockwise is positive, clockwise is negative.

The magnitude of the voltage is and the direction of the current is clockwise.

Explanation:

Given that,

Number of turns = 9

Magnetic field = 0.5 T

Diameter = 3 cm

Time t = 0.14 s

We need to calculate the flux

Using formula of flux

Put the value into the formula

We need to calculate the emf

Using formula of emf

Negative sign shows the direction of current.

Hence, The magnitude of the voltage is and the direction of the current is clockwise.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
