Slingshot Effect
Slingshot effect Suppose you throw an elastic ball to a moving train. And since the train’s mass is huge, let’s assume that the ball’s mass is negligible compared to the mass of the train. At this time, if the speed … more

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
