The electric current, in turn, creates its own magnetic field—one that ... which increases the field still further. This self-sustaining loop is known as the geomagnetic dynamo.

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...

The YIG and current loop combination provides a complex yet fully controllable medium that can be used to design a wide range of magnonic devices,” said Northeastern Universi ...

Recently, a research team found a new way to control the magnetic reversal in a special material called Co3Sn2S2, a Weyl semimetal. The team was led by Prof. Qu Zhe from the Hefei Institutes of ...

1. A wire carrying a current at right angles to a magnetic field experiences a force. List 3 ways of increasing the size of the force. 2. An electric current flows in a loop of wire in the ...

DC SQUID: A DC SQUID consists of two Josephson junctions connected in parallel in a superconducting loop. When an external magnetic field is applied, it induces a current in the loop, which is ...
