Electricity & Magnetic Fields - What do they Resemble?

In summary, when electricity flows through a coil of wire, the resultant magnetic field resembles that of a bar magnet. It is circular in shape and has north and south poles which attract and repel, similar to a bar magnet. Option c does not provide much information, so the most accurate answer would be a or b.

When electricity flows through a coil of wire, what does the resultant magnetic field resemble?

a the magnetic field of a bar magnet
b the magnetic field of a horseshoe magnet
c the magnetic field around a straight wire
d the magnetic field around a circular magnetic disc.

ok so i know that it creates a circular like magnetic field like that of a bar magnet, but I am not sure if it acts like a bar magnet also having north and south poles which attract and repel, and c doesn't really give me much to think on, so I am not sure whether it would be a, b, or d.

The question just asks what the field resembles and not what it acts like. You know it resembles that of a bar magnet.

o ok thank you
 

Related to Electricity & Magnetic Fields - What do they Resemble?

1. What is electricity and how does it flow?

Electricity is a flow of electrons through a conductive material. It is created when there is a difference in electric potential between two points, causing the electrons to move from the higher potential point to the lower potential point, creating a current.

2. How are electricity and magnetism related?

Electricity and magnetism are two parts of the same force, known as electromagnetism. An electric current creates a magnetic field, and a changing magnetic field can induce an electric current. This relationship is described by Maxwell's equations.

3. What do electric and magnetic fields look like?

Electric fields are represented by lines that point away from positive charges and towards negative charges. Magnetic fields are represented by lines that form loops around a wire or magnet. Both fields decrease in strength as distance from the source increases.

4. How do electric and magnetic fields affect everyday objects?

Electric and magnetic fields can interact with charged particles, causing them to move or experience a force. This is how electricity powers our devices and how magnets attract or repel each other. However, most everyday objects are not affected by these fields since they do not have a strong enough charge or are not magnetic.

5. What are some potential health effects of exposure to electric and magnetic fields?

There is ongoing research on the potential health effects of exposure to electric and magnetic fields, but current studies have not found any conclusive evidence of harm at levels typically found in our daily lives. However, high levels of exposure, such as those from power lines or industrial equipment, may have some health risks and precautions should be taken to minimize exposure.
