How can you classify iron and aluminum? Iron cans stick well to the magnet. However, aluminum cans do not stick well to magnets. If the conveyor belt’s last wheel is a magnet, the iron cans are stuck to the magnets … more
High frequency alternating currents are difficult to pass through the inductor. An inductor is a part made by winding a wire. In the case of direct current, the inductor only works as a lead. When an AC voltage is applied … more

Why does the current gradually increase in an inductor? As current starts to flows through the inductor, a magnetic field is created around the inductor. This magnetic field’s change generates an electromotive force. Due to the disturbance of this electromotive … more
Generally, iron is not a magnet. However, near the magnet, it is affected by the magnet and gets the magnet’s property. Therefore, iron sticks to the magnet. In this way, the material that becomes magnetic by the magnet is called … more
Charge Distribution on a thin Conductive Plate Charges on the conductor plate are assumed to be (-). The thickness of the conductor plate is assumed to be very thin. Charges on the conductor plate can move freely. Charges of the … more
Magnetic Induction When the magnet is placed close to the clip, the clip sticks. And when the magnet is attached to the refrigerator, it does not fall. Also, when two magnets are brought close together, they push or pull each … more
Direction of the Lorentz force Conductors in which current flows in a magnetic field are forced to move. The direction of this force is perpendicular to the current and the magnetic field, respectively. More precisely, we can find out below. … more
What is light? A form of energy that brightly illuminates the world we live in is called light. Various electromagnetic waves, including visible light, are emitted from hot objects or objects with energy. Visible light is the part of the … more
Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of the magnetic needle placed … more
Whenever electric charge (such as an electron) accelerates, it gives out energy in the form of electromagnetic radiation. For example, electrons moving up and down a radio antenna produce a type of radiation known as a radio wave. Electromagnetic radiation … more
A diode is an electronic component that conducts current primarily in one direction. It has low resistance in one direction, and high resistance in the other. A diode is made by joining an n-type and p-type semiconductor. n-type semiconductor: doping … more
