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

Then take a magnetic compass and move it close to it.
The NORTH seeking tip of the compass will be attracted to the South pole of the electromagnet, and vice versa.

The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
The polarity of an electromagnet is determined by what?
the direction of the flow of current
Do waves have magnetic polarity?
No, waves do not have magnetic polarity. Waves are disturbances or vibrations that propagate through a medium or space, and they do not possess magnetic properties. Magnetic polarity is a characteristic of magnetic materials such as magnets, where they have a north and south pole.
What are particles with reversed magnetic polarity?
Antimatter
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 when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
What determines where electromagnet waves fall on the electromagnet spectrum?
Frequency determines this.
What can reverse magnetic polarity make?
What can reverse magnetic polarity
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
What kind of magnet can vary its strength polarity?
an electromagnet
What type of magnet can vary its strength and polarity?
electromagnet
What kind of magnet can vary its strength and polarity?
Electromagnet
The polarity of an electromagnet is determined by what?
the direction of the flow of current
What would happen to electronics magnets etc if the earths magnetic poles changed?
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
What are the polarity of earth's north and south poles?
The magnetic polarity of the location we call 'Magnetic North' is a south pole, and the polarity of the location we call 'Magnetic South' is a north pole.
Do waves have magnetic polarity?
No, waves do not have magnetic polarity. Waves are disturbances or vibrations that propagate through a medium or space, and they do not possess magnetic properties. Magnetic polarity is a characteristic of magnetic materials such as magnets, where they have a north and south pole.
How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
