Solenoid. The solenoid is a coiled conductive wire. A solenoid can be used to increase a magnetic field that would be present in a single straight line wire. Each time a wire wraps around with current flowing the same way the overall magnetic field is intensified.

The Mineral magnetite Magnetite is best known for its property of being strongly attracted to magnet s. Some forms of Magnetite from specific localities are in fact themselves magnets. Commonly known as Lodestone, this magnetic form of Magnetite is the only mineral that is a natural magnet.

Of the following choices, the most effective way to increase the magnetic field in the interior of the solenoid is: a) Double its length, keeping the number of turns per unit length constant. b) Reduce its radius by half, keeping the turns per unit length constant.

The solenoid is commonly used to obtain a uniform magnetic field. By inserting a soft iron core inside the solenoid, a large magnetic field is produced. B = μnI = μ 0 μ 1 nI … (5) when a current-carrying solenoid is freely suspended, it comes to rest like a suspended bar magnet pointing along north-south.

The field can be visualized in terms of magnetic flux lines (similar to the lines of force of an electric field). These imaginary lines indicate the direction of the field in a given region. By convention they originate at the north pole of a magnet and form loops that end at the south pole either of the same magnet or of some other nearby magnet.

What is a solenoid? A solenoid is a long loop of wire wrapped along with a metallic core, which produces a uniform magnetic field when an electric current is passed. It uses the magnetic field created by an electric current to create linear motion. What is electromagnetic force? The electromagnetic force is a fundamental force of nature and this force is carried by …
