The magnetic effect of an electric current, also known as electromagnetism, is a fundamental principle in physics discovered by Hans Christian Ørsted in 1820. He observed that a compass needle deflected when placed near a current-carrying wire, indicating the presence of a magnetic field generated by the electric current. This discovery showed that electricity and magnetism are closely related.

When an electric current flows through a conductor, such as a wire, it produces a magnetic field around it. The direction of this magnetic field can be determined using the right-hand rule: if you point the thumb of your right hand in the direction of the current, your curled fingers show the direction of the magnetic field lines. The strength of this magnetic field depends on the magnitude of the current and the distance from the wire.

This principle is used in many practical applications. For example, in electromagnets, a coil of wire (called a solenoid) is wound around a soft iron core. When current passes through the coil, it creates a strong magnetic field that magnetizes the iron core. Electromagnets are used in electric bells, relays, motors, and various industrial machines.

The magnetic effect of current is also the working principle behind electric motors and generators. In motors, electrical energy is converted into mechanical energy through magnetic interaction. In generators, mechanical energy is converted into electrical energy using magnetic fields. This interaction between electricity and magnetism forms the basis of modern electromechanical technology and is essential in daily life.

It's used for electroplating metal objects with a protective layer of metal to minimalize damage. It's also used for electro plating implants for the hip or knee joint, since some types of metal can cause an allergic reaction and be rejected by the body after surgery. So coating the implants with a material that's compatible with living tissue and lessen the risk of an infection or the body rejecting it.

Additionally, medical implants like those for hips and knees are often electroplated to make them strong, durable, and suitable for use in the human body.

Effects of Electricity

There are for effects of electricity. They are chemical effects, heating effects, magnetic effects and harmful effects.

The chemical effects of electricity is when a chemical reaction happens when and electric current is passed through certain chemical solutions or liquids. We make use of this effect for the extraction of metals, or for electroplating an object with a thin layer of metal. This is commonly done to coat medical instruments or for coating implants.

The heating effects of electricity is when electrical current is passed through a heating element. The heating element usually consists of a wire made of a high-resistance material. This effect is are used for toasters hairdryers and incubators.

The magnetic effect of electricity is when electrical current is passed through metals which magnetizes the metal. This can be observed by dropping a magnet through a copper tube as the magnet passes the copper tube, electrical current is created magnetizing the copper tube which slows the descent of the magnet. This effect is used in MRI machines.

The harmful effects of electricity are electrical fires and electric shocks. Electrical fires happen when the power supply is overloaded, this cases excessive heat which can cause fires. Electric shock happens when electricity flows through the body causing injury or death.

# data[].attributes.body
When electric current passes through a heating element, some electrical energy may be converted to heat energy.

It's used in heating elements in everyday objects like household items that are made to withstand high temperatures. It's also used for infant incubators when a baby is born prematurely or unwell and might not be able to regulate it's own body temperature. The heating element in the incubator keeps the temperature in the incubator constant until the baby can regulate it's own body temperature.

It's also used for keeping medical instruments sterile by using the heating element to produce steam at high pressure.

The heating effect of electric current is the conversion of electrical energy into heat as current flows through a conductor. This process is used in various applications, from household appliances like toasters and heaters to industrial processes like welding.
