Question
You want to create a uniform (constant and parallel) magnetic field in a small volume of space. The field should be 0.5 Tesla, equal to the strength of the Earth's magnetic field. You can get a current of 2 Amperes from a power source, and you must choose ONE of the following methods:a) A single long straight wire, at a distance r from the wire
b) In between two long parallel wires spaced distance 2D apart
c) a flat coil of radius R and N turns
d)a long solenoid of length l and N turns
explain how you would get te required field. Specify the method and the physical dimensions needed.
Explanation / Answer
d) becuse in only in solenoid we can get constant magneti field and we can also control the strength of field by controlling the number of turns
