Introduction
The term magnet is defined as, an object made of a ferromagnetic material such as iron, with domains that are aligned one way. Thus, it has poles and a magnetic field around it. Magnets or electromagnets whose effect can be switched on and off are used in many electric machines. When any current flows, it produces a magnetic field.
Were it not for the Earth's magnetic field, all life on the planet would be …showed first 75 words of 1104 total…

…showed last 75 words of 1104 total…that if the number of coils is doubled, then the mass of the panel pins lifted, will also double, i.e.
5 coils will enable a lift of X grams of panel pins;
10 coils will enable a lift of 2X grams of panel pins; and
15 coils will enable a lift of 3X grams of panel pins.
Hence, an iron bar with a solenoid of N coils will lift a mass of NX grams of panel pins.
