Practicing Success
A solenoid of length $0.5 \mathrm{~m}$ and radius $10 \mathrm{~cm}$ has 500 turns. If a current of $5 \mathrm{~A}$ flows through it, the magnetic field produced inside the solenoid will be: |
1.4 × 10-3 T 2.8 × 10-3 T 4.8 × 10-3 T 6.28 × 10-3 T |
6.28 × 10-3 T |
$ B = \mu_0 nI$ $ n = \frac{N}{l} = \frac{500}{0.5} = 1000$ $\Rightarrow B = 4\pi \times 1000 \times 5 = 6.28\times 10^{-3}T$ |
