WebFactors Affecting Field Strength. The strength of the magnetic fields field depends on: The size of the current. The distance from the long straight conductor (such as a wire) A larger current will produce a larger magnetic field and vice versa. The greater the distance from the conductor, the weaker the magnetic field and vice versa. WebElectric Bell. Displaying top 8 worksheets found for - Electric Bell.

WebElectromagnets are made up of a coil of wire wrapped around an iron core. The strength of an electromagnet’s magnetic field may be increased by: Increasing the current in the coil. Adding more turns to the coil. The magnetic field around an electromagnet has the same shape as the one around a bar magnet. The field can be reversed by reversing ... WebDumping cars! /**/ A huge electromagnet is often used to pick up cars. When the current is switched off, the magnet loses its magnetism and the car falls back down to the ground. Electric motors An electric motor uses the motor effect to spin a coil of wire inside a magnetic field. To increase the speed of the motor: Increase the current in the coil. WebAlternating Current (ac) Alternating current typically comes from mains electricity and generators. It is needed for use in transformers in the National Grid (covered later in this topic) The direction of electron flow changes direction regularly. A typical frequency for the reversal of ac current in mains electricity is 50 Hz. physics in vedas
