The magnetic field inside a solenoid is-

Compare the direction of the magnetic field inside a solenoid with that of the field there if the solenoid is replaced by its equivalent combination of north pole and south pole.

(A) : A solenoid tend to contract when a current passes through it. (R) : The magnetic field inside the solenoid is uniform.

(A): Magnetic field lines can be entirely confined within the core of a toroid. But not within a straight solenoid. (R) : The magnetic field inside the solenoid is uniform.

A 3*0cm wire carrying a current of 10A is placed inside a solenoid perpendicular to its axis. The magnetic field inside the solenoid is given to be 0*27T . What is the magnetic force on the wire?

A wire is wound on a long rod of material of relative permeability mu_(r) = 4000 to make a solenoid. If the current through the wire is 5 A and number of turns per unit length is 1000 per metre, then the magnetic field inside the solenoid is

A solenoid of length 0.6 m has a radius of 2 cm and is made up of 600 turns If it carries a current of 4 A, then the magnitude of the magnetic field inside the solenoid is

A solenoid consists of 100 turns of wire and has a length of 10 cm. The magnetic field inside the solenoid when it carries a current of 0.5 A will be :

An 8 cm long wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. If the magnetic field inside the solenoid is 0.3 T, then magnetic force on the wire is

A solenoid has 1000 turns per meter length. If a current of 5A is flowing through it. then magnetic field inside the solenoid is (a) 2π X 10^-3 T (b) 2π X10^-5 T (c) 4π X 10^-3 T (d) 4π X 10^-5T

A solenoid has 1000 turns per meter length. If a current of 5A is flowing through it. then magnetic field inside the solenoid is (a) 2π X 10^-3 T (b) 2π X10^-5 T (c) 4π X 10^-3 T (d) 4π X 10^-5T
