The only question I need answered is at the bottom of the page: How would you explain the +/- readings of the digital weighing machine during the experiment?
If you would like to correct my answer to the question above this one, I would be very greatful but understand if you are unable to! thank you!

### Step 10:
Switch the leads at the power supply so that the current flows through the wires in the opposite direction to what has been done above. Repeat Steps 2 through 9 of this procedure and fill out Table 2.

![**Objective:**
The primary aim of this activity is to observe and measure how a magnetic field affects a current passing through a conductive wire. Through this exploration, several supporting objectives will be confirmed:
1. A magnetic field does not exert a force on stationary, unbound charges.
2. The magnetic force on a current in a wire is not aligned with the magnetic field direction.
3. The magnetic force on a current in a wire is not aligned with the current flow direction.
4. The magnetic force is directly proportional to both the current in the wire and the wire length within the magnetic field.
5. Understand that weight is a force.
**Theory:**
A magnetic field applies a force, \( F_B \), on a moving charged particle. The magnitude of \( F_B \) is given by:
\[ F_B = q \, v \, B \, \sin \theta \]
Where \( q \) is the charge (Coulombs), \( v \) is velocity (m/s), \( B \) is the magnetic field strength (Tesla), and \( \theta \) is the angle between the magnetic field and the direction of the charge velocity.
For a current-carrying conductor, the magnitude and direction of the magnetic force depend on:
1. The current's magnitude, \( I \).
2. The wire length in the magnetic field, \( L \).
3. The magnetic field strength, \( B \).
4. The angle, \( \theta \), between the magnetic field and the current.
The force \( F_B \) on wires is:
\[ F_B = I \, L \, B \, \sin \theta \]
This experiment maintains \( \theta \) as close to 90° as possible, simplifying Equation 2:
\[ F_B = I \, L \, B \]
**Equipment:**
- DC power supply
- Digital balance with 0.01 g readability
- DMM used as an ammeter
- Three wire lead cards
- Permanent magnets with a fixed gap
- Cardboard spacers
- Lab stand
- Pulley hanger bar
- Clamps
- Wire leads with alligator clips
**Set-Up:**
1. Connect the wire lead card in series with the DC power supply and a DMM for current measurement. Place the wire between two magnets on a digital balance, avoiding interaction.
2. Secure the wire card using a pendulum clamp on](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1f05be9b-1e3c-4a00-a08c-e9e4dbd5ac26%2Fa041745e-ebc2-4c1c-b726-ab8cf625e181%2Frmwuwf9_processed.png&w=3840&q=75)
