Example 10.5 A wire has 2 straight sections and one arc as shown in the figure. Determine the direction and magnitude of the magnetic field produced at the center O of the semicircle by the three sections individually and the total.

Example 10.7 A coaxial cable consists of a central conducting core wire of radius a and a coaxial cylindrical outer conductor of radius b. The two conductors carry an equal current I in opposite directions in and out of the plane of the paper. What will be the magnitude of the magnetic field B for a r b and b r ? What will be its direction?

Example 10.8 A solenoid of length 25 cm has inner radius of 1 cm and is made up of 250 turns of copper wire. For a current of 3A in it, what will be the magnitude of the magnetic field inside the solenoid?

A piece of straight wire has mass 20 g and length 1m. It is to be levitated using a current of 1 A flowing through it and a perpendicular magnetic field B in a horizontal direction. What must be the magnetic of B?

Calculate the value of magnetic field at a distance of 2 cm from a very long straight wire carrying a current 5 A

4) 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 ?

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]

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?

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 ?

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 ?
