Magnetic and electric field lines are visually defined by field lines. Give three points to explain how the field lines can be used to describe the characteristics of these fields.
(Not sure if needed to describe) Fm = qvBsin0, Fm = IlBsin0
The Attempt at a Solution
Farther apart lines = weaker fields?
Positive charge = fields radiate from a point charge
At every point on line, direction of field is tangeant
