what is magnetic field?
Magnetic field is defined as the relationship between the permittivity of free space,the magnitude of electric current,and distance.
Here is the formula,

here,
B= magnitude of the magnetic field
l= magnitude of electric current
R=distance
µ0=permittivity of free space
Now,using above formula we can calculate the magnetic field



Thus,the magnetic field is

Answer:
hey dream I m your big fan for u I have answered this question The third one is correct.
Given Information:
Elapsed time = t = 6 seconds
Required Information:
Distance = d = ?
Answer:
Distance = d = 2.058 km
Explanation:
We know that the speed of sound in the air is given by
v = 343 m/s
The relation between distance, speed and time is given by
distance = speed*time
substituting the given values yields,
distance = 343*6
distance = 2058 m
There are 1000 meters in 1 km so
d = 2058/1000
d = 2.058 km
Therefore, the storm is about 2.058 km away when elapse time between the lightning and the thunderclap is 6 seconds.

B. The gravity acceleration is in the same direction as the force of gravity, and thus towards the centre of the earth
