Answer:
These acts of attraction and repulsion are called “magnetism”, and the magnetic space around a magnet is called the “magnetic field”
Explanation:
After five to ten minutes of not breathing, you are likely to develop serious and possibly irreversible brain damage.
Answer:
The biggest difference is that gravity is an attractive force while electromagnetism is both an attractive and repelling force. Gravity happens between two objects depending on their masses, while electromagnetism is dependent on the objects' electric charges and the distance between them.
Explanation:
In a stronger gravitational field a given mass will have a larger weight.
Answer:
I=1.48 A
Explanation:
Given that
B=3.1 x 10⁻5 T
b= 4.2 cm
l= 9.5 cm
The relationship for magnetic field and current given as
Where
By putting the values
D=26.03 m⁻¹
I=1.48 A
