Separation of Steel and Aluminum
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
Inductor and Capacitor 3
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

Inductor and Capacitor
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
Otto Cycle at Gasoline Engines
Heat engine A heat engine is a machine that operates by moving energy from a hot space to a cold space. In this process, the heat engine converts some of the heat energy into mechanical energy. All the heat engines … more
Magnetization of Paramagnetic substance
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
Kinetic Energy and Stopping Distance
Kinetic energy All moving objects have kinetic energy. The kinetic energy Ek of an object with a mass of ‘m’ and a velocity of ‘v’ can be calculated as follows. \[E_{ k }=\frac { 1 }{ 2 } m{ v … more
Ion Exchange Resin
Magic to turn hard water into soft water Soap does not dissolve well in hard water. On the other hand, soap is well solved in soft water. This is because hard water contains calcium ions(Ca2+) or magnesium ions(Mg2+). Ions dissolved … more
Half Life Period of a Radioactive Substance
Radioactive decay The radioactive material can collapse its own nucleus structure. At the same time, the nucleus emits some small particles or energy to the outside. The emitted particles and radioactive energy can cause damage to the human body. In … more
