I have a problem with my electromagnet.

Introduction My electromagnet is in trouble. From the data you mentioned, the magnetic force will increase a lot by 140 turns, because you always increase it based on the original 70 turns, and the wire diameter is 1.

I have a problem with my electromagnet.

According to the data you mentioned, by 140 turns the magnetic force will increase a lot, because you are still increasing based on the original 70 turns, and if the wire diameter is 1, the resistance can be ignored and not calculated. ...

Of course, there are many opinions upstairs. You will find out who is right by doing an experiment. The simple method is to use the same iron nuts or nails and see how much you can absorb. after 70 rounds, how much can 140 absorb...

The conclusion obtained by doing the experiment by myself is much more interesting than the conclusion obtained here...

J 'have seen. on the Internet, static magnets generate electricity. The device does not move without energy, but it produces 6 volts of electricity.

The magnet can still be used for a long time.

When a coil of metallic object intersects the magnetic induction line in the magnetic field, an electric forceMagnetically induced motor (voltage) is generated. From a microscopic point of view, if there is a voltage difference, a current will form and the direction of the current is opposite to that of the electrons. The directional movement of electrons creates an electric current that charges an object.

It couples a paramagnetic material with a closed magnetic circuit to form an open magnetic circuit, a magnetizing coil and an induction coil, and changes the direction of the closed magnetic circuit by adding an alternating voltage to the coil magnetizing. . Electromagnetic induction in the induction coil generates electromotive force through changes in open-circuit magnetic field lines caused by changes in the direction of closed magnetic field lines.

The electromotive force is generated by electromagnetic induction in the coil. The variation in magnetic flux through the coil produces a currentinduced. The process of inserting or removing a magnet from a coil can be likened to the process by which a conductor cuts magnetic field lines.

The change in magnetic flux is only the superficial cause of the induced current. The real cause is that the charge in the coil is moved by the Lorentz force. Part of the conductor intersects the magnetic induction lines in the magnetic field, that is, the direction of movement of the conductor in the magnetic field is not parallel to the direction of the magnetic induction lines.

The principle of this device is radio wave induction (the same principle is used in current wireless charging. Invisible electromagnetic waves in the air cause the coil to obtain an electromotive force induced by alternating current electromagnetically). induction. This is not a true perpetual motion machine, it will not work in placests where there are no electromagnetic wave signals.

Just like the mineral radio made when I was a child, the whole electronic device does not have one. power supply, but he can still listen to the radio normally. One of the key components is the winding magnetic bar with complete coil.

There is also the previous transformer, which has two physically isolated coils. powered, and the other coil will produce different voltages according to the different number of turns, which is also based on the principle of electromagnetic induction

This type of static electromagnetic power generation device will fail if placed in a. large sealed iron box, because in this case the external clutter will be protected. If there is no induced radio wave, it will be what we often call electromagnetic waves. The pollution is used to provide the initial energy, and the static magnetic coilsThey cannot generate electricity. /p>
