How to make a magnetic drill press vise from an electromagnet. Relevant Formulas: The safe current of your magnetic vise is equivalent to the current of your microwave. Make sure there is no or little gaps between the work and the vise as air is not permeable to magnetic fields and magnetic field inverse proportional to distance squared. The magnetic force between a steel plate and a electromagnetic vise is approximated by: F(x,y,z) = Gradient(1/2 X V B^2). Where X is an experimental constant (scalar), V is the volume of steel plate (scalar), and B is the magnetic field vector and x,y,z is the force at that position on the steel plate. Applying that force at that position (x,y,z) would remove the work from the electromagnetic clamp. Where Gradient is (partial derivative x, partial y, partial z). For practical purposes, the only thing that is relevant to know is Force is proportional to the magnetic field squared, and the volume of the work being clamped. Magnetic field is proportional to number of turns and area of coil and current. The volume part seems reasonable, before I suspected incorrectly that it was area as the B field in a coil is proportional to area, however, I noticed that tall parts stuck better than shorter ones of similar areas showing that it is proportional to volume empirically. The B field squared is a little bit of a suprise. So it should mean that doubling the current in the electro magnet will result in 4x the strength (disregarding saturation limits in the lamination / core).

Hi man, love your video! Very good of how you explain things! I want to ask you and see if you can help me out with an answer. if I have a machine that has 240v (the one with 4 legs plug) am I able to convert the machine's volts down or that won't work? if that's the case, Can i use a 200 ft extension to power it with a generator? Thanks a lot again for the content!

I tried this at home, and I fed 6 amp to it and now my house is on fire any suggestions? Also will the heat from the current fire damage the components?

you should be able to use the heat from the fire to run a heat/carnot engine to cool down the transformer so the components are safe.

I think it’s great that you’re experimenting and making stuff n junk n things! I’d like to offer a bit of constructive criticism, I am NOT being mean: you need to relax man, calm down a little bit. Plan your videos. Make yourself a set of bullet points to keep your dialogue on track and linear so you’re not bouncing all over the place and saying “like” and “you know” and “um” constantly. And for Christ sake! Get a tripod! You’re gonna give people motion sickness. You have potential bud! Keep it up, get better. Oh! And when it comes to videos like this, don’t be like everyone else, EXPLAIN THE WIRING for supplying power. BE SPECIFIC! Good luck.
