Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following statements about magnetic field lines is true?
They originate from the south pole and end at the north pole.
They cross each other at points of strong magnetic field.
They form continuous closed loops.
Their density is inversely proportional to the strength of the magnetic field.
2. The force experienced by a current-carrying conductor placed in a uniform magnetic field is given by F = BILsinθ. What does 'θ' represent?
The angle between the current and the length of the conductor.
The angle between the magnetic field and the length of the conductor.
The angle between the magnetic field and the force.
The angle between the current and the magnetic field.
1. The region around a magnet or a current-carrying conductor where its magnetic influence can be detected is called a .
2. Magnets have two poles, a North pole and a South pole. Like poles each other, while opposite poles each other.
3. The SI unit of magnetic field strength is the .
1. Describe the right-hand rule for determining the direction of the magnetic field around a current-carrying wire.
