Magnetic field due to a current loop, solenoid

Bar magnets are rectangular objects made of steel or iron or any other element with permanent magnetic attributes and two poles, north and south. A bar magnet is designed so that when it is suspended freely, the north pole of the magnet aligns itself with the north pole of the earth.  A solenoid is defined […]

Definition: Eddy current is a current induced in a conducting coil generated due to the change in magnetic flux. It is named eddy due to its eddy-like appearance. As per Faraday’s laws of induction, eddy currents flow in closed loops. In planes, these currents are perpendicular to the magnetic field.  Taking an electromagnet and attaching

Our planet Earth is known to exhibit the celestial phenomenon of magnetism. The origin of the Earth’s magnetic field is not completely understood. But it is thought to emerge from some complicated movements and interactions between the molten outer mantle (consisting of molten iron) and the inner mantle (consisting of solidified iron) due to gravity

The strength of the magnetic field is determined by the number of lines of force per unit area of space. Magnetic fields are created either by the flow of current through a conductor or by the presence of some magnetised material known as magnets. Magnetic force is polarised, i.e., the magnetic force is the strongest

A permanent magnet, often known as a magnet, is a lodestone that can absorb iron compounds. This form of adsorption might linger for years without being cleared. Separating the magnet and iron components requires the introduction of an outside force. Magnet materials come in a variety of shapes and sizes. Strong magnets are made of

Magnetism is a phenomenon where magnets attract or repel magnets in their magnetic field. The magnetic field is the region around a magnet where it exerts its magnetic effect of either attracting or repelling a magnet. Our planet earth is also known to exert the phenomenon of magnetism.  The magnetic field of the earth is

The realm of geomagnetism is a new field that has emerged to understand the geological processes along with the Earth’s inner layers. William Gilbert is known as the pioneer of the field of geomorphology. The Earth acts like an enormous magnet that embodies a magnetic north and magnetic south poles. These magnetic poles are situated

The measurement of electric current was not so precise and accurate during earlier days. Electric current is measured by the intensity of the field of a magnet. After the invention of galvanometers, the measurement of electric current became easy. Galvanometers are instruments made to measure electric current. Working principle of a galvanometer The working principle

When the induced currents of doubled magnetic flux change, the conductor placed in the flux gets Eddy current. The induced currents look similar to that of whirlpools or eddies, and therefore got their name.  It can be technically defined as follows: Eddy currents are loops of current in the conductor occurring by applying to change

The motion of electric charge causes attractive and repulsive forces among objects, which is known as magnetism. The powerful magnetic effects are seen at the ends of all magnets. These are where the magnet’s poles are. When two magnets are put near each other, they exert a force on each other. The attraction and repulsion
