can you make an electromagnet with ac current
Electromagnet The energy loss per cycle of the AC current is constant for each of these processes, so the power loss increases linearly with frequency.
Electric current The consequence of this convention is that electrons, the charge carriers in metal wires and most other parts of electric circuits, flow in the opposite direction of conventional current flow in an electrical circuit.
Electrical conductor While pure water is not an electrical conductor, even a small portion of ionic impurities, such as salt, can rapidly transform it into a conductor.
Hall effect Hall probes are often used as magnetometers, i.e. to measure magnetic fields, or inspect materials (such as tubing or pipelines) using the principles of magnetic flux leakage.
Galvanic cell In addition, electrons flow through the external conductor, which is the primary application of the galvanic cell.
Inverter (logic gate) If no specific NOT gates are available, one can be made from NAND or NOR gates, because NAND and NOR gates are considered the "universal gates",[1] meaning that they can be used to make all the others.
