Facts about Magnets and Electricity will inform the readers with an electromagnet. A solenoid is considered as the simplest form of electromagnet for it consists of a coiled wire. The magnetic field will be formed when an electric current passes the coiled wire. When there is not electric current, it will stop acting like a magnetic field. Let us get other useful facts about magnet and electricity by reading the whole post:
Facts about Magnets and Electricity 1: the magnetic field
The magnetic field is mainly focused inside and near the coiled wire. The similarity of a magnet and electromagnet is spotted on the field lines.
Facts about Magnets and Electricity 2: the right hand rule
The right hand rule is used to define and determine the orientation of an effective magnet.
Facts about Magnets and Electricity 3: the magnetic field and magnetic moment
The cross section of each loop in the coiled wire, the number of wire loops and electrical current will determine the magnetic field and magnetic moment.
Facts about Magnets and Electricity 4: the weak magnetic field
You will produce a weak magnetic field if the material without magnetic properties is used to wrap the coil of wire.
