Q1 A very long wire is placed through the center of a 5 cm long solenoid of 200

Question

Q1

A very long wire is placed through the center of a 5 cm long solenoid of 200 turns per meter ( 1 cm diameter) and each carries a current of 2 amperes in the same direction. using amperes law determine the magnetic field 3 cm from the center of the solenoid that is 2 cm outside it. Using U"sub knot " as the permeability constant.

Q2

A coil of wire of 5000 turns is placed in a region of space where a magnetic field is decreasing at 2 teslas/second. if the plane of the coil is placed 45 degrees to the field dircetion and its area is .01 square meters, determine the current induced in the coil if the coil is connected to a 45 ohm resistor. assume that the coil itself has a 5 ohm resistance.

Explanation / Answer

B=magnetic constant*NI/L

B being the MF
N the turns
magnetic constant:4pi*10^-7
L= the length
I= the current
