Here is how the Depth of Permanent Magnet equation looks like.

0.1118 = 0.26 \cdot \frac{0.02 \cdot 4.3}{0.2}

0.1118m = 0.26m \cdot \frac{0.02Ω \cdot 4.3m}{0.2Ω*m}

0.1118 = 0.26 \cdot \frac{0.02 \cdot 4.3}{0.2}

Depth of Permanent Magnet Solution

Follow our step by step solution on how to calculate Depth of Permanent Magnet?

FIRST Step Consider the formula

D = T \cdot \frac{R e \cdot B}{ρ}

Next Step Substitute values of Variables

∴

D = 0.26m \cdot \frac{0.02Ω \cdot 4.3m}{0.2Ω*m}

Next Step Prepare to Evaluate

∴

D = 0.26 \cdot \frac{0.02 \cdot 4.3}{0.2}

LAST Step Evaluate

∴

D = 0.1118m
