In what do electromagnetic waves cause disturbances when they transfer energy?
O A. Magnetic fields only
B. Neither electric nor magnetic fields
C. Electric fields only
D. Both electric and magnetic fields

it becomes positively charged by charging it

the higher the current the higher the mag field around it the higher the influence on the compass

i don't understand. explain it clearly

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
