As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.
Where is the electromagnet the strongest?
An electromagnet is stronger if there are more turns in the coil of wire or there is more current flowing through it. A bigger bar or one made of material that is easier to magnetize also increases an electromagnet’s strength.
Where is the field strongest in the magnetic field?
The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are least dense at the center and densest between the two poles just outside the bar magnet.
How are the strongest electromagnets made?
Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.
Where is the magnetic field the strongest and why?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)
Where is the magnetic force the strongest in a magnet?
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
Where is the magnetic field the strongest on poles?
The magnetic field is strongest at the poles, where the field lines are most concentrated. Field lines also show what happens to the magnetic fields of two magnets during attraction or repulsion.
Which of the following has strongest magnetic?
The strongest permanent magnets are known as neodymium magnets and are made from an alloy of neodymium, iron and boron. Permanent magnets are difficult to magnetise as unlike magnetically soft materials their atomic magnetic domains aren’t easily aligned but once they are aligned, they remain so indefinitely.
Where can we find electromagnets?
Some everyday devices that have electromagnets inside them include:
- Microphones, speakers, headphones, telephones and loudspeakers.
- Electric motors and generators.
- Doorbells and electric buzzers.
- Computer hard drives.
- Multiple household appliances.
How powerful is an electromagnet?
Teslas measure the pull of a magnetic field. Even one tesla is quite powerful. The Earth’s magnetic field is about 50 microteslas. … Electromagnets as strong as 1,000 teslas have been created before.
