Depicts the portrait of Ányos Jedlik. To the right of the portrait, a simplified version of the cross of Saint Benedict is visible, with the initials "Crux Sancti Patris Benedicti" ("Cross of Holy Father Benedict"). Encircling the sides along the edge, the inscription "THE DESCRIPTOR OF THE DYNAMO PRINCIPLE" is present. Above the portrait, "ÁNYOS JEDLIK" is displayed, parallel to the right edge of the coin, "1861" is positioned, and below the portrait, the inscription "1800-1895" can be read. In the bottom right corner, the engraver's privy mark is placed.

Depicts the Jedlik dynamo. Beneath the depiction, enclosed within a border, the phrase "THE UNIPOLAR SELF-STARTING MACHINE" is presented. Underneath the border, the words "HUNGARIAN" and "REPUBLIC" are arranged in two horizontal lines. Positioned above the dynamo illustration, in a single line, the currency denomination and the text "FORINT" are prominently featured. To the left of the denomination, beneath it, the mint mark "BP." is depicted, while on the right side, below the "FORINT" inscription, the year of release "2011" is clearly visible.

In 1827, Jedlik engineered a prototype of a self-rotating electromagnetic apparatus, which can be viewed as an early version of the modern dynamo. His dynamo comprised a rotating copper disk adjacent to a coil of wire. Rotation of the disk induced an electric current in the coil through electromagnetic induction. This pioneering dynamo exemplified the fundamental concept of generating electricity from mechanical movement.
