Magnetic Effects of Current

The Lorentz Force is the force exerted on a charged particle as a result of the interaction of electrical and magnetic fields. A charged particle in an electric field will always be subjected to a force due to the field of magnitude F=qE, regardless of its charge. It is only when the charged particle is […]

To induce magnetism, we need a magnet. Let us first understand what a magnet is. A magnet is any object that can generate its very own magnetic field. Any object or material can be a magnet if it can generate a field of its own. Every magnet has two poles on either side, namely the

All material in the universe has magnetic properties because all materials in the universe have electrons which are tiny little magnets. It depends on what that material is as to how to respond to the magnetic field. If an object is placed inside a magnetic field they are going to respond in one of three

In 1820, Hans Christian oersted showed that an electric current might alter the course of a magnetic needle. The first galvanometer was invented after this event. The multiplier was invented by physicist Johann Schweigger and a German mathematician, and it was named after them. A galvanometer consists of a needle that is attached to a

Before trying to understand what is the relation between magnetisation and magnetic intensity, we must start by understanding the basics, including magnetic dipole and magnetic intensity. A magnetic dipole is a tiny and generally microscopic magnet. It is equal in size to the flow of an electric charge around a loop. On the other hand,

Magnetic Field can be defined as a region near a magnet where magnetic effects can be experienced. When a charged particle is placed near a current-carrying wire, there is no force on the given charge particle. But, when the charge is projected with some velocity near the same current-carrying wire, it experiences some force. This

Concept of magnetic field A magnet is a material which has the property to attract small pieces of iron, cobalt, nickel, etc. The magnet material has a specific space around it, within which its influence can be experienced. However, all magnetic phenomena result from forces between two charges in motion. The concept of the magnetic

Magnetic fields and electric current can be generated by magnets. When a charged particle passes through a magnetic field, a magnetic force is exerted on them. At the rest position, these particles are unaffected by the magnetic fields, but as they begin to move, the magnetic field pushes at them.  A uniform or steady magnetic

The force applied to any charged particle due to magnetic and electric fields is known as Lorentz force. Both the fields apply different forces, and the value of the force varies to a large extent. In the case of a magnetic field, the charged particle will feel a force that moves in the direction of

In 1820, HC Oersted proved that electric current creates a magnetic field around it. Michael Faraday observed this and believed that if an electric current can create a magnetic field, then a magnetic field can also create a current. In 1831, Faraday showed the world that if a magnet is moved inside a copper coil,
