Ferromagnetic materials – examples, origin & properties

Most of the materials are affected by the magnetic field. These materials are magnetic materials. These materials can show magnetic properties. The origin of magnetic moment in these materials is the rotation of orbital electrons around the nucleus. On the basis of the magnetic properties of materials, there are five types of magnetic materials – … Read more

Types of magnetic material | non-magnetic material

The origin of magnetism is the motion of charged particles. In every atom, there are some electrons and protons. As the electrons are revolving around the nucleus and also spinning around their own axes, the atomic system behaves like a magnetic dipole. Therefore, atoms can produce a magnetic field or can have a magnetic moment … Read more

Biot-Savart Law of Magnetism and its formula

We have discussed the origin and definition of magnetic field. A bar magnet, a current-carrying wire and a moving charge are the origins of magnetic field. Then we learned to find the direction of magnetic field in another article. Now, how to find the magnitude or value of the magnetic field? Biot-Savart law of magnetostatics … Read more

Electricity Transformer formula – Step up & Step down

Electricity Transformer is an electrical component which transfers the alternating electric power from one circuit to another circuit keeping the frequency of signal same. It can change the amplitude of alternating voltage to our desired value at the output. But the power remains same both at primary and secondary coil. In this article, I’m going … Read more

Magnetic force on a current carrying wire – expression

A current carrying wire placed in external magnetic field will experience some magnetic force. This is a similar to the force between two magnets. Because we know that a current carrying conductor behaves like a magnet. Also, It will show the same interactions like other magnets when it is placed in front of a magnet. … Read more

Properties of Magnetic field lines with diagram

Earlier we have discussed the Electric field and Electric field lines. Similar to the electric field lines, there exist magnetic field lines in a Magnetic field. In this article, we are going to discuss the definition and the properties of Magnetic field lines and the diagram of magnetic field lines for a bar magnet, solenoid, … Read more

Intensity of Magnetic Field – formula, definition (1 Tesla)

If we bring a bar magnet near another bar magnet then a force acts between the magnets. Same poles of magnets repel and opposite poles attract each other. This interaction is very similar to electric charges, but not exactly. Now question is, what makes this to happen? The answer is the magnetic force in magnetic … Read more

How to find the direction of Magnetic field? Thumb rule

Scientist Hans Christian Oersted first observed the deflection of a magnetic needle or compass placed near a current carrying wire. This concludes that the current carrying wire can produce a magnetic field around it. In another article, we have discussed the Origin, definition, unit and dimension of magnetic field. Since, the magnetic field is a … Read more
