Quick Answer: What Is The Strongest Area Of Magnetism In The Field?

What is the biggest magnet on Earth?

The biggest magnet on the planet is the earth itself.

The earth consists of a relatively shallow crust atop a thick, rocky mantle.

Under the mantle is a dense core of liquid metal (mostly iron) surrounding a solid-metal center..

At which point is the magnetic field strength greatest?

Question: The diagram below shows the lines of magnetic force between two north magnetic poles. At which point is the magnetic field strength greatest? Answer: (B) has the greatest magnetic field strength because it is located at the highest density of magnetic field lines.

What is a high magnetic field?

A magnetic field is produced by an electrical current in a metal coil. This current exerts an expansive force on the coil, and a magnetic field is “high” if it challenges the strength and current-carrying capacity of the materials that create the field.

What happens if you break a magnet in half?

You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

What is the end of a magnet called?

A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. We say the magnets repel each other.

How do you break a magnetic field?

If you want to block out magnetic “force,” your best bet is to re-route magnetic field lines (lines of magnetic flux) around the object that is sensitive to those lines. Do this by shielding the object in a material with a much higher magnetic permeability of the surrounding materials.

Are 2 magnets stronger than 1?

Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.

Why you can Demagnetise a permanent magnet by heating it?

Demagnetize a Magnet by Heating or Hammering If you heat a magnet past the temperature called the Curie point, the energy will free the magnetic dipoles from their ordered orientation. The long-range order is destroyed and the material will have little to no magnetization.

What is the strongest magnetic field possible?

When a magnetic field gets stronger than about 500,000 Gauss, objects get ripped to pieces by the intense forces. For this reason, scientists cannot build a machine that creates a magnetic field stronger than 500,000 Gauss and survives longer than a fraction of a second.

Where is the magnetic flux density greatest?

Lines of Force from a Bar Magnets Magnetic Field As shown above, the magnetic field is strongest near to the poles of the magnet were the lines of flux are more closely spaced. The general direction for the magnetic flux flow is from the North ( N ) to the South ( S ) pole.

Is the Earth’s core magnetic?

The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core.
