Question Hi there,
Thanks in advance for reading this question. It may seem a little strange. I have a hypothetical situation I would like to get some advice/info on.
Let's say I have an electromagnet connected to 20 wires. When I switch on the electromagnet, obviously all 20 of the wires become magnetized. Is there any way/any technology I can add into the equation to control which wires are magnetized and which wires remain un-magnetized? I want to be able to choose specific wires to magnetize while still having all wires connected to the electromagnet. Is this impossible? Is there anything I can use to make this possible?
Answer Let's go back to the beginning about electromagnets.
The magnetic field is created when current passes through the coil wrapped around the iron material (if an iron core is being used; or could be open air). The magnetic field does not exist if there is no complete circuit for current to pass through the wire coil.
You can use several coils, each with its own drive circuit to create at magnetic field an operate each one independently if that is what you are wanting to do.
