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
Energize your electromagnet.
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.
An electromagnet is a coil of wire usually wound around an iron core. The magnetic polarity is determined by the direction of the current.
Power determines the power of an electromagnet. Power is equivalent to volts times amps. Power is power.
The electromagnet (polarity) is determined by the direction of current.
the direction of the flow of current
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.
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.
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
The polarity of the electromagnet reverses.
Frequency determines this.
What can reverse magnetic polarity
The electromagnet (polarity) is determined by the direction of current.

an electromagnet

the direction of the flow of current
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.
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.
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.
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
