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 0.325 m^2. it is squished to have no area in 0.225 s. what is the magnitude of the average induced emf in volts if the uniform magnetic field has a strength of 1.5 t?

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

What is the speed of an object at a given moment?

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
