Draw the electric field surrounding a positive and negative point charge. Similarly, draw the magnetic field surrounding a bar magnet with a North and South pole. In what ways are magnetic poles very different from electric charges?
Homework Answers
A positive charge always produces electric filed radially out ward and A negative charge always produces electric filed radially inward.
so, Elelctric filed lines start at positive charge and end at negative charge.
But magnetic filed lines are always closed loops.They do not have a starting point and ending point.
