A rectangular loop of wire, abcd, is next to a very long straight wire. The straight wire is given an electric current, i, as shown in the picture.
(1) If i is constant, then within the loop area of the wire there is a magnetic field uniform with value of \frac{\mu_0i}{2πh}
(2) If i is constant and the wire loop is kept away from the straight wire continuously, then the wire loop will appear induced emf.
(3) If i increases, the induced current appears in the wire loop in a→b→c→d direction
(4) If i decreases, an induced magnetic field appears on the wire loop which is outward in the direction of the field
