Read each question carefully and answer to the best of your ability. Show all work for calculation problems.
1. Which of the following statements about magnetic field lines is INCORRECT?
They originate from the North pole and end at the South pole.
They never intersect each other.
Their density indicates the strength of the magnetic field.
They are purely imaginary lines and have no physical existence.
2. What is the SI unit of magnetic field strength?
Ampere (A)
Tesla (T)
Volt (V)
Watt (W)
1. A moving electric charge produces a field.
2. The direction of the magnetic field around a current-carrying wire can be determined by the hand rule.
3. The Earth's magnetic field protects us from harmful radiation.
1. Draw the magnetic field lines around a bar magnet. Clearly label the North and South poles and indicate the direction of the field lines.
2. State two differences between magnetic poles and electric charges.
1. Magnetic monopoles exist in nature.
True
False
2. The magnetic field inside a solenoid is uniform.
