Magnetic Forces and Induction Setups

The setup below is pretty nice for induction across coils, done by either flipping a switch or varying the power supply manually. Here’s a short video. You can also grab the slinky coils and change the coil density to induce current. Here’s a quick look, and another.

This setup below is good for exploring how changes to magnetic flux can induce current. You can squeeze the loop, rotate the loop, or move it into and out the field. Here is a short video showing how it works.

This rails and rod setup can be used for either induction or a rail gun. It’s similar in look and feel to many textbook rail gun problems. Here is a short video I put up.

Below is the “classic” University of Washington Tutorials magnetic force on a wire set up.
