All my points answer me right now i have 3 inutes no guesses th assuming a current is flowing, what increases the strength of the magnetic field of a coiled electrical wire? select all that apply. straightening the wire changing the direction of the current flow adding more coils to the wire placing a metal bar within the coils stopping the current

Hello there!

Straightening the wire will "diffuse" the strength of the magnetic field.

changing the direction of the current will change the direction of the magnetic field.

adding more coils will increase the magnetic field because each coil can create a magnetic field of his own, and you can add them up.

Placing a metal bar within the coils the metal can be polarized by the electromagnetic field of the coil, wich will increment the magnetic field.

Stopping the current will stop the electromagnetic field generated by the coil.

so the answers are:

Adding more coils and placing a metal bar within the coils.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
