Electromagnets can easily be turned on and off.
Explanation:
An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil".
When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.
Answer:
The correct options are MACROPHAGES AND NEUTROPHILSE.
Explanation:
Majority of the white blood cells in humans are specialized phagocytic cells, examples of these are macrophages, neutrophilse, monoctyes, mast cells and dendritic cells. The major functions of phagocytic cells is to protect the human body from disease pathogens. They do this by ingesting foreign bodies that are found in the body.
