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
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
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 is an electrical component that transforms the alternating electric power from one circuit to another circuit with the same frequency of the signal. It can change the amplitude of alternating voltage to a desired value at the output. But the power remains the same both at the primary and secondary coil. In this … Read more
A current-carrying wire placed in an external magnetic field experiences a magnetic force. This is similar to the force between two magnets. Because a current-carrying conductor behaves like a magnet. Also, It will show the same interactions as other magnets when it is placed in front of a magnet. Even if we place two current-carrying … Read more
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
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
Scientist Hans Christian Oersted first observed the deflection of a magnetic needle or compass placed near a current-carrying wire. This concludes that a 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 vector quantity, … Read more
