a) direction of magnetic field will be out of paper.
it can be determined by right hand rule.
b) direction of current will be clock wise. this too is determined by right hand rule

A circular loop of wire of radius 5cm lies in the plane of the
page. There is magnetic pointing into the page increasing at a rate
of 0.01T/s. This results in an EMF in the loop of:
a. 7.9 x 10-5 V in the clockwise direction looking into the
page.
b. 7.9 x 10-5 V in the counter-clockwise direction looking into
the page.
c. 0.01 V in the clockwise direction looking into the page.
d. 0.01 V in the counter-clockwise...

The figure shows a stationary conducting loop adjacent to a horizontal current-carrying wire. For which of the following conditions will a counter- clockwise induced current circulate in the stationary loop? Stationary conducting loop O Counter- clockwise induced current - Current-carrying wire The current in the horizontal wire flows to the right and its value is increasing. The current in the horizontal wire flows to the right and its value is constant. The current in the horizontal wire flows to the...
A very long wire and a square loop of wire lie in the plane of the page as shown. Each side of the square is 15 cm in length, the resistance of the loop is 0.6 Ω, and the near side of the loop is 3 cm from the long wire. The current in the long wire is to the right and is increasing. At the moment, the current in the long wire is 6.5 A. The magnetic flux through...
