Final answer:
The power supply for an electromagnetic drill should never be placed below the drill on a vertical wall.
Step-by-step explanation:
The power supply for an electromagnetic drill should never be placed below the drill on a vertical wall.
When an electromagnetic drill is placed on a vertical wall, it uses the magnetic field produced by an electromagnet to secure itself to the wall and provide stability. If the power supply is placed below the drill, gravity will pull the drill away from the wall, causing it to lose its grip.
It is important to ensure that the power supply is located above the drill or positioned in a way that does not interfere with the drill's ability to maintain its grip on the wall.
