A flat coil consists of 20 turns each of area

an area of 50 cm2, is positioned perpendicularly to a uniform magnetic field that increases its magnitude at a constant rate from 2.0 T to 6.0 T in 2.0 s. If the coil has a total resistance of 0.40 ohms , what is the magnitude of the induced current?

A circular conducting loop is in a region of magnetic field B directed out of the page, as shown below. The magnitude of the magnetic field is decreasing. The direction of the induced current in the loop is

The figure shows a bar magnet moving vertically upward toward a horizontal coil. The poles of the bar magnets are labeled X and Y. As the bar magnet approaches the coil it induces an electric current in the direction indicated on the figure (counter- clockwise as viewed from above). What are the correct polarities of the magnet?

A conducting ring is moving from left to right through a region that contains a constant magnetic field as shown in the diagram. In which region is there an induced current in the ring?

A uniform 4.5 T magnetic field passes perpendicularly through the plane of wire loop 0.10 m² in area. What flux passes through the loop?
