How can you show that electric currents create magnetic fields?

Check all that apply.

If you place two wires with currents perpendicular to each other, they will be attracted each other.
If you place a magnet near a closed circuit with current flowing, it will exert a force on the circuit wires.
If you place a coil of wire near a magnet and direct a current through the coil, it will exert a force on the magnet, depending on its orientation.
If you position a charge near a wire with a current, it will be attracted or repelled by the wire.

Answer #1

>if two wire is perpendicular to each other then force due to magnetic field will be zero...hence first option is incorrect...

> current carrying wire create magnetic around it..if magnet and wire put together then there will be force on wire duet to magnet....hence it is correct..

> in the same way this option is also correct...

> the rest charge will not experiance any force due to the current carrying wire....because a force is experianced due to mutual creation of magnetic fields...here rest charge can't create the magnetic field hence will not experiance a force....

although if the charge is moving then it will be forced by current carrying wire....

hence it is incorrect...

If two parallel wires have current running in the same direction, do the wires attract each...
If two parallel wires have current running in the same direction, do the wires attract each other or repel each other due to their magnetic interaction? My attempt so far: I'm imagining two parallel wires oriented vertically with the current flowing "downwards" (in the negative y direction) in each. In this case, I believe there's a circular magnetic field that wraps around and surrounds each respective wire in the clockwise direction (when looking directly downwards at each wire). Can you...

A magnetic field, strength 3T, has a direction out of the page. A loop of wire sits in the field and on the plane of the page (area vector of loop is out of page). The loop is much smaller than the extent of the field. The magnetic field starts to slowly change at a rate of -0.0001T/s. Looking down on the loop, which statement is correct? A. Magnetic flux out of page decreasing; anti-clockwise current induced in loop B....

Magnets carrying very large currents are used to produce the uniform, large-magnitude magnetic fields that are required for magnetic resonance imaging (MRI). A typical MRI magnet may be a solenoid that is 2.0 m long and 1.0 m in diameter, has a self-inductance of 4.4 H, and carries a current of 750 A. A normal wire carrying that much current would dissipate a great deal of electric power as heat, so most MRI magnets are made with coils of superconducting...

There are three neutral wires that carries a current each(Ix, Iy, Iz), they are all perpendicular to each other on the x, y, z plane. The currents are flowing from -∞ to +∞ in the positive directions in all three of them. 1. Consider the magnetic field that is very far from the origin of these wires. If we two times it's distance to the origin along the diagonal line( x = y = z), by what factor has the...

If you pass a current through a wire, you can create a magnetic field. In this class we examine the field from three specific configurations: an infinitely-long straight wire, a compact loop of wire (possibly with multiple turns, a coil), or an infinitely long solenoid (think of an infinitely-long cylinder of loops made by wrapping a single wire). See the text for an extended description of all three geometries. Here’s the challenge: there are three slightly different formulas used to...

If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...
