Transistor There are so many switches inside your computer that you can’t imagine. It’s not the hand-pressed switch we’ve been seeing. It is a switch operated by an electrical signal. The computer counts ‘1’ and ‘0’ … more
The structure of the water molecule Water is a representative ‘polar molecule’. The hydrogen-oxygen-hydrogen bonds that make up the water molecule have an angle of 104.5˚ and appear curved. Because of this unbalanced water molecule structure, … more
Energy band and band gap of atom According to Niels Bohr’s atomic model, electrons subordinate to an atomic nucleus do not have continuous energy. Electrons can only have sparsely defined energies. This is why lines in … more
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 … 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 … 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 … 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 … 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 … 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 … 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 … 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 … more
