Question

3. a) (4 points) Compare and contrast magnetic and electric fields. Your answer should include at least 2 ways they are similar and 2 ways that they differ.
b) (4 points) Include a diagram of an electric field for a positive test charge and a diagram for a typical bar magnet. Make sure you show the field lines (including direction) and label the charges and poles.

Answer 1

A magnetic field is a field explaining the magnetic influence on an object in space.

A electric field is a field defined by the magnitude of the electric force at any given point in space.

What are magnetic field and electric fields?

A magnetic field is a field explaining the magnetic influence on an object in space.

A electric field is a field defined by the magnitude of the electric force at any given point in space.

The difference between magnetic fields and electric filed are:

Electric Filed

• Magnetic fields creates an electric charge in surrounding.
• It is measured as newton per coulomb, volt per meter.
• An electric field is measured using an electrometer.
• It is proportional for the electric charge.

Magnetic Filed:

• Magnetic filed creates an electric charge around moving magnets.
• It is measured as gauss or tesla.
• The magnetic field is measured using the magnetometer.
• It is proportional to the speed of electric charge

Similarities between Electric and Magnetic Field

• Both are vector quantities
• Both are measurable
• Both produce attraction and repulsion forces
• Both are proportional to electrical charge
