Answer

When the current is passed through an electric circuit it produces some magnetism which can be detected with the deflection in compass needle.this phenomena is known as magnetic effect of electric current.

Answer

The Magnetic Effects of Electric Current

Electricity and magnetism are closely related phenomena. The magnetic effects of electric current refer to the creation of a magnetic field when an electric current flows through a conductor. This relationship was first discovered by Hans Christian Oersted in 1820 and forms the basis for various applications in power generation, electromagnetism, and technology.

Key Concepts:
1. Magnetic Field: A magnetic field is a region around a magnetic material or a current-carrying conductor where magnetic forces are exerted. It is represented by lines of force called magnetic field lines.
2. Conductor: A conductor is a material that allows the flow of electric current. Examples include metals like copper and aluminum.
3. Electric Current: Electric current is the flow of electric charge through a conductor. It is measured in amperes (A).
4. Right-Hand Thumb Rule: The right-hand thumb rule is a technique used to determine the direction of the magnetic field around a current-carrying conductor. According to this rule, if we point the thumb of the right hand in the direction of current flow, then the curled fingers represent the direction of the magnetic field.

Magnetic Field around a Current-Carrying Conductor:
When an electric current flows through a conductor, a magnetic field is generated around it. The magnetic field lines form concentric circles around the conductor, with the conductor at the center. The direction of the magnetic field can be determined using the right-hand thumb rule. If the current flows in the upward direction, the magnetic field lines will circulate counterclockwise around the conductor, and if the current flows downward, the magnetic field lines will circulate clockwise.

Magnetic Field Strength:
The strength of the magnetic field depends on several factors, including the magnitude of the current, the distance from the conductor, and the material surrounding the conductor. The magnetic field strength is directly proportional to the current flowing through the conductor. Increasing the current increases the magnetic field strength, while decreasing the current weakens the magnetic field.

Applications:
The magnetic effects of electric current have numerous practical applications, including:

1. Electromagnets: Electromagnets are temporary magnets created by passing an electric current through a coil of wire. They find wide applications in various devices such as electric motors, generators, speakers, and magnetic resonance imaging (MRI) machines.
2. Electric Motors: Electric motors convert electrical energy into mechanical energy using the interaction between magnetic fields and electric currents. They are used in appliances, vehicles, and industrial machinery.
3. Transformers: Transformers are devices that use the magnetic effects of electric current to change the voltage and current levels in AC power transmission and distribution systems.
4. Magnetic Levitation: The magnetic effects of electric current are utilized in maglev trains and magnetic levitation experiments, where the repulsion or attraction between magnets and electric currents allow objects to levitate or move without friction.

In conclusion, the magnetic effects of electric current involve the creation of a magnetic field around a current-carrying conductor. Understanding this relationship has led to the development of various technologies and applications that are essential in our daily lives.

Answer

Magnetic effect of current is a term used to establish a relationship between the flow of electric current and generation of magnetic field. To be more specific, it refers to the phenomena of generation of magnetic field around an element/wire when electric current is passed through it.

Answer

When electric current is passed through an electric wire ,it creates magnetic field around it ! This can be tested by bringing a compass near it ! During we observe the deflection of neele
