The polarity of an electromagnet can be determined by the right-hand rule. If the direction of the current flow is known, curl your right hand fingers in the direction of the current flow. Your thumb points in the direction of the north pole of the electromagnet.

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.


The what of an electromagnet is determined by the direction of current flow?

The polarity of an electromagnet is determined by the direction of current flow. When current flows one way, the magnetic field is oriented in one direction, and when it flows the other way, the magnetic field is oriented in the opposite direction.


How can the polarity of an electromagnet be determined if the direction of current flow is unknown?

The polarity of an electromagnet can be determined using the right-hand rule: wrap your fingers around the coil in the direction of the current flow (conventional current flow is from positive to negative), with your thumb pointing in the direction of the magnetic field. The side of the coil where your thumb points is the north pole of the electromagnet.


The polarity of an eletromagnet is determined by the?

the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.


What happens if you reverse the current flow in an electromagnet?

Reversing the current flow in an electromagnet changes the direction of the magnetic field it produces. This can be useful for changing the polarity of the electromagnet or controlling the direction of a mechanical system it is used in.

What kind of magnet can vary its strength and polarity?

An electromagnet can vary its strength and polarity by controlling the flow of electric current through its coil. By changing the direction and intensity of the electrical current, an electromagnet can easily adjust its magnetic field characteristics.


What happen to an electromagnet's field if the direction of the current ic reversed?

If the direction of the current in an electromagnet is reversed, the direction of the magnetic field surrounding the electromagnet will also reverse. This change in direction will affect the polarity of the electromagnet, causing its north and south poles to switch.


What determines the magnetic polarity of an electromagnet?

Neodymium Iron Boron (NdFeB or NIB) would be the stongest material of an magnet.(Is the tempature which for this material is 12,800 . Hc is the lenth of the material which is 12,300. BHmax is the strenth which is for this material 40 . The other strenth for other materials are 26, 5.5,3.5 . The highest was 40


When the direction of current flow is reversed the current of an electromagnet swap over?

When the direction of current flow is reversed in an electromagnet, the magnetic poles also reverse. This means that the north pole becomes the south pole and vice versa. So, the current in the electromagnet determines the polarity of the magnetic field it produces.


In an electromagnet why is changed by flipping the direction of the electrons which is controlled by the commutator?

Changing the direction of the current in the electromagnet by flipping the direction of the electrons through the commutator changes the direction of the magnetic field generated by the electromagnet. This is because the magnetic field produced by a current-carrying wire is directly related to the direction of the current flow. By reversing the current direction, the polarity of the magnetic field is also reversed, which allows for control over the attractive or repulsive forces exerted by the electromagnet.


What happen when you change the direction of current in an electromagnet?

If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".


How do you reverse the magnetic field of an electromagnet?

To reverse the magnetic field of an electromagnet, you can either reverse the direction of the current flowing through the coil or change the polarity of the power supply connected to the coil. This will change the direction of the magnetic field produced by the electromagnet.
