A magnet sitting next to a wire does not induce a current in the wire because <span> the magnet is very small and short compared to the coil radius. If you pretend it's two individual monopoles, they're only a few mm apart, so at several cm there's almost perfect cancellation of the fields.</span>
Answer: To solve for the net magnetic field of two circular loops of wire, each containing a single turn
B net= √[( NUI / 2R)^2 × ( NUI / 2R)^2]
Where B net = Net magnetic field
B net = √2 × (NUI/ 2R)
B net =[ √2 × 1 × ( 4 × 3.142 × 10^-7) × (1.8)] ÷ 2 × 0.034
B net = { 1.414 × (0.00000126) × (1.8)}÷ 0.068
B net = 4.72 × 10^-5 T
If an object that is 86kg on the moon then that is the answer, 86kg.
Yhuihoifjhh <span>F = Gm1m2 / r^2
if the masses are doubled then the force is increased by a factor of 4
if the distance is doubled the force is decreased by a factor of 1/ 2^2
the net result is no change in force</span>
Answer:
D
Explanation:
calculate effective resistance of the resistors
= 80 + 120
= 200
overall resistance = 48 ohms
so overall current flowing through circuit
I = V / R
I = 12 / 200
I = 0.06 A
since circuit is in series, current is same at every point so...
potential difference across 80 = R x I
= 80 x 0.06
answer is potential difference = 4.8 V
