What Uses an Electromagnet to Measure Electric Current? A galvanometer is a measuring instrument that uses an electromagnet to measure electric current. A galvanometer is an absolute instrument; it measures the electric current in terms of a tangent of deflection angle. A galvanometer can measure ...
The magnetic field involved in electromagnetic induction is typically generated by an electromagnet with a varying electric current, known as alternating current (AC). As the electrical current alternates and collapses continuously at a given frequency, the magnetic field similarly fluctuates. This ...
How does moving a magnetic field create an electric field? What determines the strength of a magnetic field? What is a magnetic field made of? What is the source of a magnetic field? How to increase the magnetic field of an electromagnet. What generates the magnetic field in a current carr...
Transformers Transformer is a passive electrical device that converts voltage and current through electromagnetic induction. There are two types of transformer: the step-up transformer and step-down transformer. The underlying physics that govern the operation of transformers is the Faraday's Law of ...
State two ways by which the strength of an electromagnet can be increased. What is grounding? What effect does it have on a charged conductor? On a charged insulator? A steel rod of length 1 m rests on a smooth horizontal base. If it is heated f...
