Answer 1:
By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak.
Answer 2:
The Effect of the Number of Coils on an Electromagnet On Its Strength. affect an electromagnet's strength. The concept of electromagnets is fairly simple. connected to a battery, will enable the nail to pick up paper clips.
Answer 3:
Dry cells come in many varieties.... The small dry cells used in watches and other electronic equipment have a strong metal case, so leakage is ... The effect is amplified at heavier drains.
Answer 4:
Cosmetics applied on the nail encompass three types: (1) coatings that harden upon evaporation; (2) coatings that polymerize; and (3) stick-on nail dressings (synthetic covers). The adverse reactions induced by the two first types present with both local reactions and distant contact dermatitis. Whereas nail enamel applications result especially in ectopic contact dermatitis, polymerizing coatings and synthetic covers represent the main culprit for sometimes severe, local reactions.

Answer:
Electromagnet is a temporary magnet made by winding a current carrying wire around a soft iron.
Explanation:
1. Winding a current carrying wire around a nail, makes it a temporary magnet called electromagnet. Tighter the windings, stronger the magnetic field.
2. More the loops of coil around the nail, stronger the magnetic field.
3. More the number of dry cells, more the electric current and hence stronger magnetic field.
4. Wider and softer nail makes a stronger electromagnet.
