Question

Considering an IDEAL solenoid... The magnetic field will be... strongest near the center strongest near the edges uniform everywhere inside The magnetic field on the outside is... strongest near the solenoid almost zero near the solenoid If the current Is through the wire is increased, the magnetic field will... If the number of turns of wire is increased, the magnetic field will If the length of the solenoid is increased, the magnetic field will If the radius of the solenoid is increased, the magnetic field will

Explanation / Answer

For Ideal solenoid:

Field is uniform everywhere inside .

--------------------------------

Field outside Ideal solenoid is zero.

------------------------

Inside field, B = u0 (N / L) I

if I increases then B will be larger.

If N increased then B will be larger.

if L increaes then B will be smaller.

B is independent of radius henc e

if r is increased then B stays same,
