What is demagnetization? What are the precautions to be taken while handling magnets?

demagnetization: remove magnetic properties from.

Explanation: While working with magnets one should not-

1.Bring the magnets near any magnetic appliance which works with electricity.

2.They lose their properties when heated, hammered or dropped from some height.

3.Magnets should be separated by a piece of wood and 2 pieces of soft iron at their ends.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
