# Question: Where Is Magnetic Field Strongest?

## What causes a magnetic field?

Magnetic field due to moving charges and electric currents All moving charged particles produce magnetic fields.

Moving point charges, such as electrons, produce complicated but well known magnetic fields that depend on the charge, velocity, and acceleration of the particles..

## What is considered a strong magnetic field?

The typical strength of the Earth’s magnetic field at its surface is around a half a gauss. … There are 10,000 gauss in one tesla. The magnets that we have here at the Magnet Lab range anywhere from 20 tesla all the way up to to 45 tesla for DC fields. In pulsed fields, they can go as high as 100 tesla, and even higher.

## What material can block a magnetic field?

The short answer is: Any ferromagnetic metal. That is, anything containing iron, nickel or cobalt. Most steels are ferromagnetic metals, and work well for a redirecting shield. Steel is commonly used because it’s inexpensive and widely available.

## Where is the Earth’s magnetic field the weakest?

Southern Atlantic oceanFor best fit the dipole representing the geomagnetic field should be placed about 500 km off the center of the Earth. This causes the inner radiation belt to skim lower in Southern Atlantic ocean, where the surface field is the weakest, creating what is called the South Atlantic Anomaly.

## How can you see a magnetic field?

Field lines can be visualized quite easily in the real world. This is commonly done with iron filings dropped on a surface near something magnetic. Each filing behaves like a tiny magnet with a north and south pole. The filings naturally separate from each other because similar poles repel each other.

## Where is the strength of magnetic field?

The field strength corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called the magnetic flux. The unit of the magnetic flux is the tesla meter squared (T · m2, also called the weber and symbolized Wb).

## What is the strongest area of magnetism in the field?

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.

## What produces the strongest magnetic field?

German Lab Generates the Strongest Magnetic Field Ever CreatedCall it another victory for German design. … That’s a lot of teslas. … But we need bigger, badder magnets. … That gave them a small coil with enough strength to stand up to 50 teslas for a brief two-hundredths of a second.More items…•
