Levitating Animals

This is a video of a levitating frog. Apparently a 10 Tesla magnetic coil is being used to lift him. This is possible because pretty much all organisms have small amounts of ferromagnetic materials inside of them. And no this does not hurt the frog because the force is spread out over the entire body, but he is probably freaking out a little bit inside.

Elektrik

Personally I prefer building wall with working outlets and light switches over building a circuit in a lab, we do this in my Electric and Alternative Energy class. To me it just makes more sense, and I guess my time in physics is what gives me a good sense of how things like the electrical guts of a wall actually work. It seems like knowing how electrons flow through a system and through a switch is the basics for any circuit, functional or theoretical. However, I like that putting together a wa

POLE VAULTING

Pole vaulting is a very good example of the transfer of momentum. You are transferring energy from running down the runway into bend in the pole, and then that pole rotates after you jump, making the pole push you vertically. As a pole vaulter myself, I can say it is not all that complicated, it does not require you to be a physics student to get over the bar. However, it is super fun! It must be flying in the air and feeling the push of the pole behind you as you kick your legs up, ho

Ferro Fluid

This is an example of how magnets can be used for levitation, or hovering if you will. All this is, is simply the force of the magnet overcoming the force of gravity of the magnet and the liquid. In this way, a "hover board" would be nothing other than a force keeping something off the ground, which is just what a normal force is when you have an object sitting on the floor. However, using magnets for levitation is cool because you cannot see the force acting on the object, and the force can als
