3. With the switch open try to pick up some paper clips and tacks. What happens?4. Close the switch and try to pick up the same paper clips and tacks. What happens?You can increase the power of your electromagnet by winding more turns of wire around the nail. You could also use ...
and you can use this to make an electromagnet by wrapping a current-carrying wire around a metallic core. In addition, you’ve found that a greater voltage or more wraps of wire increases the strength
How to Make an Electromagnet Leave about a 4” end of wire loose and then tightly wrap the wire around the nail or bolt. Wrap it as many times as possible leaving just a small amount of exposed metal at each end. The more coils, the stronger the electromagnet. Secure with tape. Leave...
Superconducting magnets are a type of electromagnet that use the phenomenon of superconductivity to produce a highly strong and persistent magnetic field. It consists of coils made of superconducting materials that can carry electric currents with virtually zero resistance, allowing for a greater magnetic...
You obviously need a stronger electromagnet for a particle collider than you do for a speaker, so how do scientists make magnets powerful enough to focus a beam of electrons? The answer is a bit more complicated than simply making them bigger, although that's part of it. The materials you...
You can easily create a small electromagnet yourself by connecting the ends of a copper wire to the positive and negative ends of an AA, C or D-cell battery. This creates a small magnetic field. If you disconnect either end of the wire from the battery, the magnetic field is taken away...

2. Start Your Letter of Interest for a Job with a Hook You're the needle. The haystack is all the junk email the manager gets. How can you make sure they find you? You must learn to write a letter of interest that catches their attention like an electromagnet. You need a hook. Use...
DC electron flow is very slow and takes about 170 hours to make a 600 inch loop around an amp circuit which includes half the length of the power transformer secondary winding and half of the output transformer primary due to their center taps. Don't believe this? See electron drift ...
