Such magnets are called temporary magnets. An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.

How many atoms of S are there?
How many atoms of Br are there?How many atoms of Br are there?
Answer:
8
Explanation:
There are 8 atoms of Br because there are two molecules of 4 atoms of Br. 4 x 2 = 8.
Answer: 1 mol Br contains 6.022×1023Br atoms;its mass is 79.90 g.
Explanation:
: I mole or bromine refers to 6×10^23 molecules of bromine. But 1 molecule of bromine has 2 atoms. Hence the atom count will be exactly twice.
How do air masses flow?
from regions of low pressure to high pressure
it depends on the time of the day
from regions of high pressure to low pressure
whichever way the wind blows
