Magnetic Fields Purpose: To develop understanding magnetic poles. p an understanding of magnetic fields and the interactions betweern Materials: For this lab, you will need magnets and a compass. Electric Fields between charges, which had to be mapped using pass. For the scenarios on the following three pages, place ectric potential (voltage) since it could not be directly mapped, we can directly mar magnetic fields using a com nethe indicated positions and then place the compass at each point whe gridlines cross and mark the direction of the magnetic field by should point in the direction of the field at that location, which ic field at each location, corresponds to North on the compass. After labeling the magne in another filed maps, answer the following questions. color, sketch the magnetic field lines. When you have completed the magnetic 1) Compare and contrast magnetic poles and electric charges in terms of attraction, repulsion, and their corresponding fields. 2) As discussed in the procedure, the direction of the magnetic field is given by the North" end of th from the North Pole of a magnet to the South Pole. Discuss the implications of e needle on the compass. The magnetic filed is also defined to go applying these facts to the Earth's Magnetic Field.

Explanation / Answer

Attraction:- Opposite charges (a positive and a negative) attracts each other. Opposite magnetic poles (north and south) attract each other.

Repulsion:- Like charges (positive-positive, negative-negative) repel each other. Like magnetic poles (south-southwest, north-north) repel.

Both attractive and repulsive forces depend on the magnitude of charges or magnetic poles.

Fields:- Electric field is created by a single charge but magnetic fields are created by both the magnetic poles together.

Both the fields created by a charge and magnetic poles have directions.

Both the fields are long range fields and inversely proportional to the square of the distance from source.

Electric field point in the direction of motion of a positive charge while a magnetic field will point in the direction of travel of a North Pole.

Electric lines of force always originate at positive charge and terminate at negative charge. They never form closed loop. While magnetic lines of force point from N to S pole in outside and from S to N pole inside the liquid.

Electric fields can do work but work done by magnetic field is zero.
