Electromagnetism (article) | Khan Academy
An electromagnet is a coil of wires that becomes a magnet when electric current runs through it. Electromagnets only work when the electric current is turned on. Increasing the electric current or increasing the number of wire loops increases the strength of the electromagnet. Changing the magnetic field around a coil of wire (by moving a ...

The maximum conductivity of ETP copper occurs at approximately 200 ppm of oxygen as shown in Figure 3. Consequently, oxygen content for ETP copper is generally in the range of 175 to 450 ppm. Lower oxygen values are usually avoided because of a propensity to hot cracking resulting from uncombined impurities.
