Similarities between static electricity & magnetism
Points : Similarities between static electricity & magnetism, Right hand rule, For detection of direction of magnetic lines of forces, For detection of direction of flow of current
Remarkable similarities between Static electricity and magnetism are as follows.
• There are two types of charges, positive and negative. There are two types, of magnetic poles, North and South.
• Like charges and like poles repel each other, opposite charges and opposite poles attract each other.
• Charged objects set up electric fields of force, he magnetic objects set up magnetic fields of force.
• Certain substances may be electrically charged by rubbing together, certain magnetic substances may be magnetized by rubbing with another magnet. Right hand rule: Statement: James Clark Maxwell gave a rule relating the direction of the magnetic lines of force round a wire to the direction of the current flowing through it. This is known as right hand rule. For detection of direction of magnetic lines of forces: Imagine the wire to be grasped in the right hand with the thumb pointing along the wire in the direction of the current. The direction of the fingers will give the direction of the magnetic lines of force. For detection of direction of flow of current: Hold the wire in the extended right hand curling the fingers in the direction of lines forces. The thumb will show the direction of current in the wire.
