Two electromagnets are made with the same core and the same type of wire. Electromagnet A has a low-intensity current, and electromagnet B has a high-intensity current. Which statement about the electromagnets is correct? (1 point)

If they produce the same strength magnetic force, then they must have the same number of turns in the
wire

If they have the same number of turns in the wire, then electromagnet A has a stronger magnetic force.

If they have the same number of turns in the wire, then they must have the same strength magnetic force

If they produce the same strength magnetic force, then electromagnet A has more turns in the wire.

this a false

explanation:

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
