An iron rod with diameter of 1.5-centimeter was formed into an almost perfect circular ring (including the air gap at the joint) having an average centerline radius of 10.0-centimeter. The air gap is 0.25 centimeter in length. A coil of 200 turns was wounded on the ring and a current of 5.0-amperes DC was made to flow using external DC source. Considering magnetic flux fringes on the air gap ,  the effective cross sectional area of the air gap increased by 5% compared to that of the rod.  Relative Magnetic Permeability of Iron = 5500.  Consider the average or centerline circumference of the ring as the total magnetic path (rod+airgap).   1. What is the total Reluctance of the ring ( rod + air gap ) (A-turns/Wb) ? 2.What is the magnetic flux generated in the ring? 3. What is the magnetic flux density in the air gap

Consider a time-varying electric field intensity E = E cos(wt - Bz) that exists everywhere in free space. Use Faraday's law to determine the corresponding magnetic field intensity H. You may assume there is no DC (constant) component. Use Ampère's law on your expression for H to find E and solve for ß in terms of w.

An infinitely long wire carrying a current of 7.12 A is bent into the shape shown in the figure. The angle the arc subtends is 0 = 63° and the radius of the arc is 0.11m. Find the magnitude and direction of the magnetic field at the point P which is at the center of the arc.

A long wire is bent into the hairpin-like shape shown in the figure. a) What is the direction of the magnetic field at the indicated point P, which lies at the center of the half-circle? b) What is the magnitude of the magnetic field at that point? (Hint: At the center of a circular current loop of radius R, the loop's magnetic field has magnitude Bloop, at center = Hoi / 2R.) d. c) Suppose an electron is at rest at point P. What force does the magnetic field exert on it? i
