Artificial Magnetic Fields — Electromagnetism (Physics Gr12)

In summary, the conversation discusses the magnetic field strength between two parallel conductors carrying 10 A of current in the same direction. The first question asks about the field strength at the midpoint between the wires, which is determined to be 0T. The second question considers the field strength if the current ran in opposite directions, resulting in a field strength of 4.0x10^-4T. The conversation also suggests using the right hand rule and drawing diagrams to better understand the concept.

Homework Statement


Two parallel conductors each carry 10 A of current in the same direction.
a) What is the magnetic field strength at the midpoint between these wires? (answer = 0T)
b) What is the field strength at the same point if the current ran in opposite directions? (answer = 4.0x10^-4T)

I am very confused and any help would be greatly appreciated

Are you familiar with the right hand rule..

Make some drawings of the magnetic field with two wires.

Yes I am familiar with all three of them
 
  • #4
Then I suggest drawing two wires "end on" and adding circular B field lines around each. See what happens in the middle.

Thanks, got it
 

1. What is an artificial magnetic field?

An artificial magnetic field is a magnetic field that is created by humans using electromagnetic devices. Unlike natural magnetic fields, which are produced by the Earth and other celestial bodies, artificial magnetic fields are man-made and can be controlled and manipulated for various purposes.

2. How are artificial magnetic fields created?

Artificial magnetic fields are created by passing an electric current through a wire, which generates a magnetic field around the wire. This can be achieved by using an electromagnet, which consists of a wire wrapped around a metal core and connected to an electric power source.

3. What are the applications of artificial magnetic fields?

Artificial magnetic fields have a wide range of applications in various fields, including technology, medicine, and industry. In technology, they are used in devices such as electric motors, generators, and speakers. In medicine, they are used in magnetic resonance imaging (MRI) machines. In industry, they are used in metal detectors and particle accelerators.

4. Can artificial magnetic fields be harmful?

While artificial magnetic fields are generally considered safe, high levels of exposure to these fields can potentially be harmful. This is especially true for individuals with pacemakers or other medical devices that can be affected by magnetic fields. It is important to follow safety guidelines and regulations when working with or near artificial magnetic fields.

5. How do artificial magnetic fields affect living organisms?

The effects of artificial magnetic fields on living organisms are still being studied and debated. Some studies have shown that these fields can have an impact on the behavior and health of certain organisms, while others have not found any significant effects. More research is needed to fully understand the potential impact of artificial magnetic fields on living organisms.
