Explanation:
The magnet uses electromagnetic induction meaning it can be readily magnetized and demagnetized (using electricity) when required. When electricity is switched on, it becomes magnetized and lifts an object and when electricity is switched off, it loses magnetism and releases the object.
The magnetic is able to lift heavy objects because it has powerful conductor material (ferromagnetic iron) and the number of electromagnetic coils is many to induce a powerful magnetic force. The electric current, inducing the magnetism, is also powerful.

Melamine should be the right answer, i hope this helps.
Answer:
Two moles of hydrogen gas combine with one mole of oxygen gas to produce two moles of water.
Explanation:
This is the required amount of each element to synthesize water. The equation has been balanced using coefficients.
Answer is: an atom in a pure metal that's face-centered cubic has 12 neighbor atoms.
Fce-centered cubic has eight atoms at each corner of the cube and six atoms at each face of the cube.
Metals that possess face-centered cubic structure are copper (Cu), aluminum (Al), silver (Ag) and gold (Au).
There is three types of cubic cell:
1) simple cubic unit cell.
2) body-centered cubic unit cell.
3) face-centered cubic-unit cell.
