This video explains the motor effect, which occurs when a current-carrying conductor is placed in a magnetic field, creating a force between the conductor and the magnet. The video discusses how to calculate the magnitude and direction...

This is a lecture video on the differences between direct and alternating potential difference. The video defines and explains the two types of current and provides examples of each. It also includes graphs that demonstrate how potential...

This tutorial describes several different methods for removing the enamel insulation from "magnet wire," which is commonly used to make solenoids and electromagnets.

This nugget explains Ampere's Circuital law and its mathematical expressions to illustrate the relationship between electric current and magnetic field

Batteries store chemical energy that can be converted into electricity, providing a source of power. By connecting a battery to a circuit, a chemical reaction takes place, causing a buildup of electrons at the anode and creating an...

On November 22, 1963, President John F. Kennedy was assassinated in Dallas, Texas. Arguably the crime of the century, Kennedy's murder stunned the American people and set off an outpouring of grief around the world. But the days after...

Sometimes physics and nature go hand in hand. In this video we’re going to look at using Fleming’s left hand rule to help us remember how current, magnetic fields and direction go together.

Electromagnets are incredibly useful. They can do all the things a normal magnet can do, but can also be switched on and off. Electromagnets have many uses, from moving cars in a scrap yard to high speed Maglev trains. The trains are...

A tutorial for a 9W light bulb smart home system. The light bulb fixture is connected to a 5V relay module as well as to the mains. An android smartphone (with app) is used to turn the light bulb on and off. ESP32S microcontrollers with...

Transformers change the potential difference of electricity. There are two main types of transformer that are used in the national grid. These are step up and step down transformers. Each of them consists of a two coils of wires around...

A light bulb has the glass carefully removed, leaving the glass base and filament intact. The bulb is connected to AC electricity, and the filament quickly and dramatically burns out. This leaves the two wires that originally...

This video is a lecture on electrical power. The concept of power in electrical appliances is discussed, along with how to calculate the power of an electrical appliance. The video demonstrates using the equation to calculate the power...

This nugget explains about the conductors and insulators and activity on identification of conductors and insulators.

It explains resistance, factors affecting the resistance of a wire and resistivity or specific resistance.

When a current passes through a wire it produces a magnetic field. If you put this magnetic field in another magnetic field, it puts a force on the wire. This is known as the motor effect. To determine the direction of the force you use...

This video explains how to calculate the magnitude of the force acting on a conducting wire when it is placed in a magnetic field. The video starts by explaining the motor effect and how a current carrying conductor experiences a force...

Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet. Turn up the voltage in this experiment, and make that current strong...

This nugget explains the construction, mathematical derivations and applications of a potentiometer device.
