<span>Nickel and cobalt are ferromagnets. This means that they are able to acquire magnetism from induction by an external magnetic field. This is caused by the realignment of atoms and unpaired electrons in  their structure induced by the magnetic field. Aluminum and copper don't get magnetized because they have few unpaired electrons in their atomic structures.   </span>

Answer:
Spoilage microbes produce acid
Explanation: 
When food becomes spoiled or is unprotected, bacteria will invade the food. These types of bacteria are called spoilage bacteria. The bacteria will multiply by consuming the nutrients from the food and grows very rapidly. In certain conditions, the invading bacteria will produce acids that protects them and creates a barrier for other microbes. This acid is what gives spoiled food a sour taste.
