You are given a solenoid of length'l', number of turns per unit langth.'n' and area of cross section A.When a current'I' passes through it.What is the self- inductance of the solenoid?

A steady current of 1 amperes is passed through a long solenoid of length 1 and number of turns N When an alternating! current is applied to an electrical element, the current in it leads the voltage by pi//2 . Identify the- element.

A magnetic field of 100 G (1 G = 10^(-4)T) is required which is uniform in a region of linear dimension about 10 cm and area of cross-section about 10^(-3) m^(2) . The maximum current carrying capacity of a given coil of wire is 15A and the number of turns per unit length that can be wound round a core is at most 1000 turns m^(-1). Suggest some appropriate design particulars of a solenoid for the required purpose. Assume the core is not ferromagentic.

A closely wound solenoid of 2000 turns and area of cross-section 1.6x10-^4m^2 , carrying a current of 4.0A, is suspended through its centre allowing it to turn in a horizontal plane. Br What is the magnetic moment associated with the solenoid?

A closely wound solenoid of 2000 turns and area of cross-section 1.6x10-^4 m^2 , carrying a current of 4.0A, is suspended through its centre allowing it to turn in a horizontal plane. Br What is the force and torque on the solenoid if a uniform horizontal magnetic field of 7.5x10^2 is set up at an angle of 30° with the axis of the solenoid?
