From Wikipedia:
"A synovial joint, also known as diarthrosis, joins bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces. The synovial cavity/joint is filled with synovial fluid."
Given Information:
Amplitude of the electric field = E = 570 N/C
Speed of light = c = 3.0x10⁸ m/s
Required Information:
Amplitude of the magnetic field = ?
Answer:
Amplitude of the magnetic field = 1.90x10⁻⁶ T
Explanation:
The relation between the amplitude of the electric field and magnetic field is given by
B = E/c
Where c is the speed of light
B = 570/3.0x10⁸
B = 1.90x10⁻⁶ T
Therefore, the amplitude of magnetic field is 1.90x10⁻⁶ T
