The magnetic field at a point inside the solenoid of infinite length is given by B=___________. (here ′n′′𝑛′ is the number of turns per unit length)

f the number of turns in a solenoid is increased, the strength of the magnetic field producedwill

Describe the magnetic field of a solenoid.

A solenoid of 1200 turns is wound uniformly in a single layer on a glass tube 2 m long and 0.2 m in diameter. The magnetic intensity at the center of the solenoid when a current of 2 A flows through it is:

Field inside a solenoid is A Directly proportional to the current flowing through the coil B Directly proportional to its length C Inversely porportional to total number of turns. D Inversely proportional to current.

The strength of magnetic field inside a long current carryingstraight solenoid is(a) more at the ends than at the centre(b) minimum in the middle(c) same at all points(d) found to increase from one end to the other
