Physics

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

Explanation:

No. of turns N = 300

Radius r = 0.040 m

Length of solenoid $L= 40 \times 10^{-2}$ m

Current I = 12 A

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

$B = \frac{\mu _{o} NI }{L}$

Where $\mu _{o} = 4\pi \times 10^{-7}$

$B = \frac{4 \pi \times 10^{-7} \times 300 \times 12}{40 \times 10^{-2} }$

$B = 11.3 \times 10^{-3}$ T

B = 11.3 mT

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