A solenoid with 300 turns has a radius of 0.040 m and is 40 cm long. If this solenoid carries a current of 12 A, what is the magnitude of the magnetic field near the center of the solenoid? (μ 0 = 4π × 10-7 T · m/A)

The magnitude of the magnetic field near the center of the solenoid is 11.3 mT

Explanation:

No. of turns

Radius m

Length of solenoid m

Current A

For finding the magnetic field near the center of the solenoid is given by,

Where

    T

    mT

Therefore, the magnitude of the magnetic field near the center of the solenoid is 11.3 mT

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
