The magnetic field at the centre of a circular current carrying loop of radius 12.3 cm is 6.4 × 10-6 T. What is the magnetic moment of the loop?

Magnetic field at a distance 2.4 cm from a long straight wire is 16 µT. What must be current through the wire?

Current of equal magnitude flows through two long parallel wires having separation of 1.35 cm. If the force per unit length on each of the wires in 4.76 × 10⁻² N, what must be I ?

A very long straight wire carries a current 5.2 A. What is the magnitude of the magnetic field at a distance 3.1 cm from the wire?

Two wires shown in the figure are connected in a series circuit and the same amount of current of 10 A passes through both, but in apposite directions. Separation between the two wires is 8 mm. The length AB is S = 22 cm. Obtain the direction and magnitude of the magnetic field due to current in wire 2 on the section AB of wire 1. Also obtain the magnitude and direction of the force on wire 1. [µ0 = 4π × 10⁻⁷ T.m/A]

An alpha particle (the nucleus of helium atom) (with charge +2) is accelerated and moves in a vacuum tube with kinetic energy = 10.00 MeV. On applying a transverse a uniform magnetic field of 1.851 T, it follows a circular trajectory of radius 24.60 cm. Obtain the mass of the alpha particle. [charge of electron = 1.62 × 10⁻¹⁹ C]

An electron is moving with a speed of 3 × 10 6 m/s in a magnetic field of 6.00 × 10⁻⁴ T perpendicular to its path. What will be the radius of the path? What will be frequency and the kinetic energy in keV ?
