Can't get enough of hands-on electromagnetic experiments? We have some more ideas for you to try: What is the magnetic power of a single coil wrapped around a nail? Of 10 turns of wire? Of 100 turns? Experiment with different numbers of turns and see what happens. One way to measure and compare a magnet's [...]
Electromagnets All Around Us Many electromagnets have an advantage over permanent magnets because they can be easily turned on and off, and increasing or decreasing the amount of electricity flowing around the core can control their strength. Modern technology relies heavily on electromagnets to store information using magnetic recording devices. When you save data to [...]
Electromagnetic Lock An electromagnetic lock, magnetic lock, or maglock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking devices are [...]
How does an electromagnetic lock work? electromagnetic lock work - An electromagnetic lock creates a magnetic field when energized, causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening, according to HangSeng Magnetech Inc. most cases, the armature plate is on the edge of the door, [...]
Electromagnetic - Electromagnetism is one of the four fundamental interactions of nature, along with strong interaction, weak interaction and gravitation. It is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields. Electromagnetism is the force responsible for practically all the phenomena encountered in daily [...]
