(a) Derive an expression for the magnetic field a distance r from an infinitely-long straight wire carrying current i. [I want a complete derivation.] (b) Two infinitely-long, straight wires are located 0.5 m apart and carry current into the paper. The wire on the left carries a 5 A current while the wire on the right carries a 2 A current. What is the magnitude and direction of the magnetic field at a point half-way between the wires?
Starting from the magnetic field at a distance h about the axis of a circular loop of radius R through which a current circulates I. Show that when h ≫ R the field approaches that of a magnetic dipole. Find how far one has to go for the dipole approximation to be within 1% of the true field
A circular wire loop of radius 22.0 cm carries a current of 4.90 A. It is placed so that the normal to its plane makes an angle of 90.0° with a uniform magnetic field of magnitude 12.0 T. Calculate the magnitude of the magnetic dipole moment of the loop. (Your result must be in units of A.m 2 and include 3 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take π = 3.14.)
