The current direction inside the battery is reversed
4. Is the direction of the deflection the same as in Step 4, before the leads to the battery were reversed? Is the amount of the needle''s deflection the same as before? 5. Suppose something is flowing in the wires. Do you think the direction the needle is deflected is caused by the amount of the flow or the direction of the flow?

Questions and Answers
If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism. ... If the direction of the electric current is reversed, the magnetic field reverses also and circles the wire in a clockwise direction. If you wrap some ...

Battery Circuit Diagram: Understanding the Positive and Negative …
The positive terminal, often represented by a longer line or a plus sign (+), is where the current flows out of the battery. On the other hand, the negative terminal, usually indicated by a shorter line or a minus sign (-), is where the current flows into the battery. These terminals establish the direction of current flow within the circuit.
What Happens to a Battery If You Charge It Backwards? (Here is …
This is because when you charge a battery, the chemicals inside the battery are forced to flow in one direction. If you charge a battery backward, the chemicals will flow in the wrong direction and this can cause them to break down.

Solenoid Magnetic Field: Definition and Equation
Then, the direction of the magnetic lines of force inside the solenoid is from left to right. If the direction of the current is reversed, the polarity will reverse as well. The magnetic lines of force are also analogous to that of a bar magnet. They are straight and parallel and follow a longitudinal path inside the solenoid.

How to deal with the current going opposite direction through …
In the most traditional circuit, current flows out of the positive terminal into the negative terminal. That is, it flows from the long bar to the short bar, so clockwise here. This means …
The direction of electric current
This is the direction of the actual current flow. Direction of current flow in circuit analysis. In terms of circuit analysis, we normally consider the direction of electric current from positive to negative. Mathematically, negative charge flowing in one direction is equivalent to positive charges flowing in the opposite direction.
