Question

question 5

ceramic magnetic materials mixed with liquids can be used to make magnetic ink, which is used on checks.
true
false

Explanation:

Analyze the composition of magnetic ink

Using the Ferrites and Magnetic Recording Media knowledge points

$$ \text{Ceramic magnetic materials} = \text{Ferrites (e.g., iron oxide powders)} $$

These powdered ferrites are suspended in a liquid carrier medium to create magnetic ink.

Verify the application on checks

Using the Magnetic Recording Media knowledge point

$$ \text{Application} = \text{Magnetic Ink Character Recognition (MICR)} $$

This specialized ink is printed on the bottom of bank checks to allow automated reading by MICR equipment. Therefore, the statement is true.

Answer:

• True (Correct answer)
• False
