Magnectic field and electrical interaction

In summary, a magnetic field can be detected by its effects on other magnetic materials and moving electric charges. The force exerted by the magnetic field is perpendicular to both the velocity of the moving charge and the direction of the magnetic field. This can be seen in a visual representation of a ~300 volt electron beam in a vacuum tube inside a Helmholz coil. The equations and concepts may be complex, but there are resources available for further reading and understanding.

simple question from a beginner to physics, in wikipedia it states that a magnetic field can be detected by its affects on a moving electrical charge, but does "not" go onto say how an electrical charge is affected by magnetic fields, is the current weakened/distorted or am i swinging in the dark here, my question is could someone give a detailed explanation as to the relationship between electrical current and magnetic fields, or could someone provide a link to some reading material on this subject.

"Quote From Wikipedia" and is detected by the force it exerts on other magnetic materials and moving electric charges

thanks very much, a lot of that article is far above my current knowledge on the subject but its very interesting reading, the equations are very complex to my eyes but it did answer my question :)
thanks

A picture is worth 1000 words and 100 formulas. See the thumbnail of a ~300 volt electron beam in a vacuum tube inside a Helmholz coil. The deflection force is perpendicular to BOTH the beam velocity AND the direction of the magnetic field. Residual gas in the vacuum tube is excited by the beam as it passes.

interesting Bob, and true the image does help explain visually what I am trying to read in the above site, thanks very much
 

FAQ: Magnectic field and electrical interaction

What is a magnetic field?

A magnetic field is an invisible force field created by moving electric charges. It is represented by lines of force that show the direction and strength of the magnetic field.

How are magnetic fields and electrical interaction related?

Magnetic fields and electrical interaction are closely related because both are caused by the movement of electric charges. Electrical currents create magnetic fields and magnetic fields can induce electrical currents.

What are some examples of electrical devices that use magnetic fields?

Some examples of electrical devices that use magnetic fields include motors, generators, transformers, and speakers.

How can you measure the strength of a magnetic field?

The strength of a magnetic field can be measured using a device called a magnetometer. This device can detect the direction and magnitude of a magnetic field.

Can magnetic fields be harmful to humans?

In general, magnetic fields are not harmful to humans. However, exposure to very strong magnetic fields, such as those in medical devices, can have negative health effects. It is important to follow safety precautions and guidelines when working with strong magnetic fields.
