Question

These two questions have me quite confused. Can someone showme how to work through these? Thanks in advance, I will ratelifesaver!

1) A solenoid of 200 turns carrying a current of 2 A has alength of 25cm. What is the magnitude of the magnetic fieldat the center of the solenoid?

*(answer= 2mT)*

2) The maximum current in a superconducting solenoid can beas large as 3.53 kA. If the number of turns per meter in sucha solenoid is 2430, what is the magnitude of the magnetic field itproduces?

*(answer= 10.8T)*

Explanation / Answer

No.of truns N = 200

Current I = 2A

Length L = 25 cm =0.25 m
