The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
You can detect the magnetic field by its pull on another magnet, including a compass needle.
Electrical current is nothing but movement of electrons in case of metals. It causes heating and produces magnetic field.
An electrical generator does that.
An electric current produces a magnetic field.
Yes to all. -- Electrical current in a toaster produces thermal energy, often known as "heat". -- In a light bulb produces light. -- In the wires dangling from eaqr-buds produces sound. -- In a solenoid coil or motor stator produces magnetic forces.
All electrical circuits produce a magnetic field around the wires when a current is travelling. If we want to generate a large field, we can coil the wire. Such a coil is called a solenoid.
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
Any device with an electrical current will create a magnetic field. A tube of wire coils with a current running through it is called a solenoid and it will produce a magnetic field through the inside of the tube, as well as around it... Sorry, not much for physics.
A magnetic field can induce an electrical current in a wire.
Electric current produces magnetic fields around the conductor through which it flows, according to Ampère's law. Additionally, electric current also generates heat due to the resistance of the material through which it passes.
An electromagnet, a coil of wire round a magnetic core. An electric current in the wire produces a magnetic field round the core, which contains energy which could be used to lift a load.
