A.c. current and induced force

In summary, A.C. current is a type of electrical current that changes direction periodically, while D.C. current flows in only one direction. A.C. current is generated by rotating a coil of wire in a magnetic field and its frequency is measured in Hertz (Hz). A.C. current can affect the surrounding environment through magnetic fields and electromagnetic radiation. Its advantages over D.C. current include the ease of transforming voltages, changing frequency, and safety.

when A current-carrying conductor is placed in A magnetic field due to the interference of both magnetic fields,the field is made variable so a force will be induced on the Conductor.

so my question is, If an Ac current is passed through conductor it will have variable magnetic field will it induce a force on another object?

Yes, it will induce a variable force.

For example you can hear an activated ac-relay "buzzing" because two pieces of iron are attracked to each other by a variable force.

The force will be proportional to the current at any time.

Related to A.c. current and induced force

1. What is the difference between A.C. current and D.C. current?

A.C. current, or alternating current, is a type of electrical current that changes direction periodically. This means that the flow of electrons in the circuit alternates between positive and negative direction. In contrast, D.C. current, or direct current, flows in only one direction.

2. How is A.C. current generated?

A.C. current is generated by rotating a coil of wire in a magnetic field. This induces a constantly changing current in the wire, resulting in alternating current.

3. What is the frequency of A.C. current?

The frequency of A.C. current is the number of cycles it completes in one second. It is measured in Hertz (Hz) and in most countries, the frequency of A.C. current is 50 Hz or 60 Hz.

4. How does A.C. current affect the surrounding environment?

A.C. current can induce a magnetic field, which can affect nearby electrical devices and cause interference. It can also produce electromagnetic radiation, which can be harmful to living organisms.

5. What are the advantages of A.C. current over D.C. current?

A.C. current can be easily transformed into different voltages using transformers, making it more efficient for long-distance transmission. It is also easier to change the frequency of A.C. current, which is essential for many electrical devices. Additionally, A.C. current is safer to use compared to D.C. current.
