What generates the magnetic field in a current carrying wire? How is the magnetic field oriented around a magnet? How to find electric field from magnetic field? What is the SI unit for the strength of a magnetic field? What is the symbol for magnetic field?
Earth isn’t the only planet with a magnetic field – gas giant planets like Jupiter have aconducting metallic hydrogen layerthat generates their magnetic fields. Themovement of these conducting layersinside planets results in two types of fields. Larger motions, such as large-scale rotations wi...
When a current runs through a conductor in a magnetic field, the magnetic field generates a force at both ends of the conductor that is perpendicular to the direction of movement of the electrons in the conductor. Make a potential distinction. The major purpose of the Hall...
of Induction, which is the basis for electromagnets, electric motors and generators. A charge moving in a straight line, as through a straight wire, generates a magnetic field that spirals around the wire. When that wire is formed into a loop, the field becomes a doughnut shape, or a ...
An electromagnet is a type of magnet created by running an electric current through a conductive material. The electric current generates a magnetic field around the material, effectively turning it into a temporary magnet. The strength of the magnetic field produced by an electromagnet can be contr...
The Earth's magnetic field generates the magnetosphere that surrounds the Earth. Interaction of the solar wind with the magnetosphere causes the northern and southern lights known as the Aurora Borealis and Aurora Australis. The Earth's magnetic field also impacts the iron minerals in lava flows. ...
Anyway, I still believe in principle we can marshal magnetic field strength energy to build such a device. The problem right now is that of magnetic field strength vs distance. That is, the further away you get from a field, the less force it exerts. ...
“disturb” the magnetic flux of the permanent magnet, which causes the flux field to grow and shrink. The changes in that field are sensed, and the sensing element generates a corresponding digital pulse signal output. To determine direction, the sensor is arranged to produce a quadrature ...
Electrostatic fields and magnetic fields Electrostatic fields bear some similarity tomagnetic fields. Objects attract if their charges are of opposite polarity (+/-) and repel if their charges are of the same polarity (+/+ or -/-). The lines of electrostaticfluxin the vicinity of a pair of...
To read data, the head detects the magnetic patterns on the platters. The specific magnetization pattern tells the head whether it's a 0 or a 1. When it comes to data writing, the head generates a magnetic field that flips the polarity of the magnetic regions on the platter to create th...
