A wire loop with an area of 1.4×10−2 m2 is in a magnetic field of 0.36 T directed at a angle 30 to the plane of the loop. If the field drops to zero in 36 msms , what is the average induced emf in the loop?

A coil of 15 loops of wire is laying on the table. It experiences an increasing magnetic field going into the table. If the magnetic field goes from 0.15 T to 0.85 Tin one-third of a second and the coil has a diameter of 6 centimeters, determine the magnitude of the induced EMF and the direction of the induced current

A single circular loop of wire of radius 0.25m is positioned in a uniform magnetic field of 0.25T  that points out of the page. What is the magnitude of the average EMF induced in the loop if it's orientation changes from being in the plane of the page to out of/into the page over a time period of 0.59seconds?

A fixed 17.4-cm-diameter wire coil is perpendicular to a magnetic field 0.56 T pointing up. In 0.29 s , the field is changed to 0.35 T pointing down. What is the average induced emf in the coil?

A loop of area 225 cm2 has 24 turns of wire. It is in a magnetic field of strength 3.6 x 10-2 T. To begin with, its plane (face) is parallel to the magnetic field lines. In a time of 0.15 s it is rotated so that its plane is perpendicular to the magnetic field lines. What is the average emf induced in the loop during the one-quarter rotation?

Suppose a 50 turn coil lies in the plane of the page in a uniform magnetic field that is directed into the page. The coil originally has an area of 0.25 m2 .
