WebOct 6, 2014 · Magnetic fields are generated by electric currents. Alternating curents will produce alternating magnetic fields, so the waveform of the current really only tells you how the field strength of the magnetic field will vary with time, it says nothing about rotation with more information. There are several different types of motors. WebMagnetic fields are measured in microteslas (μT, or millionths of a tesla). Electric fields are produced whether or not a device is turned on, whereas magnetic fields are produced only when current is flowing, which usually requires a device to be turned on. Power lines produce magnetic fields continuously because current is always flowing ...

WebA magnetic field is easily created since a liquid iron is present in the planet’s core. Like any other magnets, planets do have poles. These poles are the reason for the attractive and repellant force present. Like any other magnetic field production by producing electric current, similarly the same on planets too. WebFeb 20, 2024 · Figure 22.9. 1: (a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire. (b) Right hand rule 2 states that, if the right hand thumb points in the direction of the current, the fingers curl in the direction of the field. This rule is consistent with the field mapped for ...

WebAs Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field … WebThen, in the 19th century, scientists studying the relatively new field of electrical currents discovered that moving charges produce magnetic effects. A current traveling through a loop of wire creates a magnetic field along the axis of the loop. The direction of the field inside the loop can be found by curling the fingers of the right hand ...

WebThe phenomenon of the interaction of electric currents or fields and magnetic fields ... But now with this single experiment, we are seeing that electric current is producing magnetic field.
