Electromagnets: Two Forces Team Up Resistive electromagnets, another type of temporary magnet, combine the powers of electricity and of magnetism to enormous effect. Although superconducting electromagnets, which we'll discuss soon, offer many advantages, certain laws of physics prevent them from reaching the field strengths electromagnets are capable of. Some of the world's most powerful resistive [...]
Electromagnetic Transmissions Solenoids Holding Magnets Solenoids for simple operation Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass. Solenoids for [...]
Energise to Hold Electromagnets / standard Electromagnets / Solenoid/Electromagnet Electrical current is required to turn the magnet ON. Power is removed to turn the magnet OFF. Pull force conversion (approximate): 1kg = 10N = 2.2lb. The outer shell of the electro magnet is a sturdy bright nickel plated cylinder, passivated with body mounting. Designed for [...]
Electromagnet or solenoid are general terms for all types of electromagnetic actuators. Basically, electromagnets or solenoids are devices that generate a magnetic field by means of an energized coil, guiding it through suitable iron parts with air gap. Here, magnetic poles are created inbetween which a magnetic force of attraction, the magnetic force, prevails. If [...]
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 [...]
