1. The magnetic field, pointing in the opposite direction as the area vector of a 0.02m^2 loop, has an instantaneous value of 7T. What is the magnetic flux through the loop in SI units? Hint: Be careful with signs.

2. The magnetic field, pointing perpendicular to the area vector of a 0.02m^2 loop, has an instantaneous value of 7T. What is the magnetic flux through the loop in SI units?

3. The magnetic field, pointing in the same direction as the area vector of a 0.02m^2 loop increases by 1T every second. What is the induced EMF, in Volts?Hint: Be careful with signs.

4. What are all the ways that you can change the magnetic flux through a wire loop? Select all true statements.

You can change the magnetic flux by changing the area of the loop that is in the B-field.

At a certain location there is a constant horizontal magnetic field pointing to the east. A square loop of wire is placed in this field. At time A the bottom of the loop is resting on the floor (which is insulating), and the plane of the square loop is vertical and perpendicular to the magnetic field. The loop tips over and at time B it is flat on the floor. For this situation... A) Before the loop starts to tip...

A loop of wire sits in a uniform magnetic field, everywhere pointing toward you. Due to a changing magnetic flux through the loop, an induced current flows in the wire, clockwise as shown. The area of the loop is J. 1.63 m2 , and the magnetic field initially has magnitude K. 0.61 T. (a) Suppose that, over a time period of L. 1.47 s, the magnetic field changes from its initial value, producing an average induced voltage of M. 8.7...

A magnetic field, strength 3T, has a direction out of the page. A loop of wire sits in the field and on the plane of the page (area vector of loop is out of page). The loop is much smaller than the extent of the field. The magnetic field starts to slowly change at a rate of -0.0001T/s. Looking down on the loop, which statement is correct? A. Magnetic flux out of page decreasing; anti-clockwise current induced in loop B....

Faraday's law states that a changing magnetic field will create an electric field that curls around the magnetic field. To quantify this, we use the expression of flux (Φ) which is the magnetic field strength multiplied by the area (A) it’s passing through. This is given by: Φ = ?? The electric field is applied to the outside edge of this area. This created an electric potential that is referred to as an electro-motive force (EMF, ε). Faraday’s law can...

The illustration below shows a loop of wire with area A and a uniform magnetic field B that goes through the loop. (The field fills the whole area of the page, but it is simpler to make one drawing.) The area vector and B-field direction are both in the plane of the page. The loop is perpendicular to it, but drawn in a perspective view so that you can see it is a loop. The B-field has a constant magnitude...

A circular loop with 50 coils is pulled (to the right) from an external magnetic field of 0.8 T into the page. At t=0 the right edge of the loop is at the right edge of the magnetic field. After 0.250 seconds the loop has moved completely out of the magnetic field. Diameter of the coil is 10 cm Find the rate of change in flux through one loop as the loop if the loop is pulled out of the...
