The National High Magnetic Field Laboratory once held the world record for creating the strongest magnetic field. Their largest
hybrid magnet can produce a constant magnetic field of 45 T 45 T . To see if such a strong magnetic field could pose health risks for nearby workers, calculate the maximum acceleration the field could produce for Na + Na+ ions (of mass 3.8 × 10 − 26 kg 3.8×10−26 kg ) in blood traveling through the aorta. The speed of blood is highly variable, but 45 cm/s 45 cm/s is reasonable in the aorta.

So
Answer:
7.894 Hours.
Explanation:
Based on information number hours that this battery will last with give load has mathematical relation of.
with load 60A t = 1h, 30A t = 2h so on and forth.
two head lights draw total current of 2x3.8A = 7.6A.
putting this in above relation gives.
.
That is how long will it be before battery is dead.
