The polarity of an electromagnet is determined by what?

The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.


Will changing the polarity of the current change the polarity of the electo magnet?

Yes!


What is the overall polarity of co in the context of the current market trends?

The overall polarity of CO in the current market trends is positive.


What is polarity in welding?

Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.


Can a magnet destroy an IC?

No a integrated circuit IC for short is solid state and can only be destroyed by reverse polarity or shortened output or to high input tension or current No a integrated circuit IC for short is solid state and can only be destroyed by reverse polarity or shortened output or to high input tension or current


What is alterneting current?

a current that keeping on changing its polarity with time is called alterneting current

Does a diode have polarity?

Yes, a diode inherently has polarity, as current is only allowed to flow one direction.


Does Direct current have constant amplitude and polarity?

yes


Explain welder polarity?

Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.


What happens when you reverse the current in a current-carrying magnetic field?

The polarity of the electromagnet reverses.


Does galvanometer have polarity?

No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
