What happens to a magnetic field if the current carrying wire a has three times as many loops but the same current as the current carrying wire b?
wire a will have a lower magnetic field than wire b.
wire a will have a magnetic field one–half as strong as wire b.
wire a will have a magnetic field that's greater than wire b.
wire a and wire b will both have the same magnetic field.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
